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.
Before fixing `test-js-with-puppeteer` to to use the right webpack
setup, redirects weren't happening properly. The line this commit
removes did a redirect to the register page. This line is removed
as the redirect will happen automatically as expected with fixing
`test-js-with-puppeteer`.
