Now that all casper tests have been migrated to
puppeteer, there's no need for having casper
related things.
Removed the casperjs package and removed/replaced
casper in few places with puppeteer.
Only removed few of them which I'm confident
about. Also didn't make any changes in docs
as it would be easier to remove them while
adding puppeteer docs.
The next adds a few tests which heavily rely on
check_messages_sent. There were some weird errors,
this fixed those. I think the errors were due to
us navigating multiple times and this function
not waiting for the messages to become visible.
Also add helper functions needed.
`select_item_via_typeahead` has been ported from casper
and is exactly same in puppeteer to as I couldn't find
any better way for that purpose.
When messages weren't locally echoed,
`wait_for_full_processes_message` fails to assert that the message
is being sent. It was figured out by tabbott that the messages
aren't locally echoed because of content no loading completely.
So, this commit changes the `log_in` function to wait till
the selector '#zhome .message_row' is visible which indicates
that the cotent is loaded.
Removed the waitForNavigation in the `log_in` as it would
become a redundant check after this change.
Also removed this same check present in 03-compose.js which
becomes reduntant as we already do it in `log_in`.
ES and TypeScript modules are strict by default and don’t need this
directive. ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

There were a lots of flakes in CI recently because typeahead didn't
appear when Enter was pressed and real emails are not accepted as
valid inputs. To fix this we wait for typeahead to appear and then
click that instead of Enter. We also use delay option to type the
email (100ms delay between keypresses) since without we'd also get
flakes.
Re-enable puppeteer test in CI after this fix too.
Prettier would do this anyway, but it’s separated out for a more
reviewable diff. Generated by ESLint.

The flake was caused due to the fact that current_msg_list was not
populated with any messages in rare cases. We were missing a check
to guard against current message list having no messages. The
failure screenshot show no messages to prove this.
Relevant error:
Evaluation failed: TypeError: Cannot read property 'raw_content' of undefined
The get_rendered_messages now returns a Map, that is formatted as:
{
'Verona > topic 1': ['message 1', 'message 2'],
'You and Cordelia Lear': ['private message 1']
}
We also add check_messages_sent (which was expected_messages in
casper). It now takes in a object, formatted similar to
get_rendered_messages above, instead of an array with topic and
messages.
We include all method needed from casper except
get_rendered_messages, and expected_messages. We will want to tweak
their API when we migrate them.
We also rename bunch of method here while migrating them.
Waiting till DOMContentLoaded event is triggered helps avoid flakes since
puppeteer is very fast and starts doing another task before
everything on the page is loaded. Adding this to log_in function
as almost all tests depend on this which leads to flaky tests if
the other parts of tests just start without even the page being
loaded.
One example this commit helps is for the test `02-site.js`
which is dependent on a function that runs some jquery on the site.
But because of the page not being loaded, we miss jquery and thus
the test fails. `02-site.js` and related code is added in the next
commit.

When no credentials are sent to `log_in` function we want to
use the default generated test credentials. This saves us the
work of importing test_credentials everytime we run this function
in a different test which doesn't focus on what credentials are sent
to login.
To take a screenshot on failure where we have our common error
handling code in common.run_test method we need to have access to
the Page instance. Currently, we create a new Page in the test method
we pass into run_test, so we pass in a new Page instance to that method
so the test and the run_test method have access to the same Page. And,
then we take a screenshot on failure. It will be saved as `failure-${num}`
in var/puppeteer directory.
In common.js, we now have a single browser instance for the whole
test. When we update the test-js-with-puppetter to spawn a single
node process, like we do for node tests, we will save time on having
to open an new browser for every test + puppetter start up cost.
We will also add some more helpers here like a method for
filling out a form easily etc.
