Some files already were using `noop` in place of `() => {}`.
It's both clearer what it means and is easier to type.
This updates all test files to fully use `noop`, and
adds a shared import from the test lib file.
Throughout the codebase there is currently one usage of `autofocus`
excepts in test files. The only one usage is in `signup.js` and was
supposed to pass a `JQuery` selector to `autofocus` rather than a
string. Passing a selector is more convenient in this case: The
selector accessed in `signup.js` is ready to `trigger` the `focus`
function, while getting a attirubte string from the selector and then
passing to `autofocus` and then accessing the selector by attribute
cost extra layers of work. Therefore writing this commit to simplify
the type for easy usage.
Fixes the test case(s) accordingly.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
