We were using a custom icon because in the past social-share-button
didn't have support for whatsapp. But now that it does, we can remove
our custom icon.
Note we're using the `_app` suffix because that's the name of the icon
meant for mobile devices.
We were doing the same tests three times to test the advanced search
feature. I'm grouping them in one place and shuffling the sections
around to remove duplication and make the test suite faster.
We were repeating the same code over and over (with a few variants) to
setup tests which require an administrator. We can use a tag and
simplify the code.
We weren't using `foundation()` in these cases, so after flagging a
debate or a comment, we had to reload the page before we could unflag
it.
We're also adding a test for the fix in commit ea85059d. This test shows
it's necessary to filter the elements with JavaSctipt using `first()` if
we want the same code to work with comments.
