The button to select/deselect a proposal wasn't very intuitive; for
example, it wasn't obvious that pressing a button saying "selected"
would deselect the proposal.
So we're using a switch control, like we do to enable/disable features
since commit fabe97e50.
As mentioned in the previous commits, a `<select>` field which submits
its form on change causes many accessibility and usability issues, so
we're replacing it with the order links we use everywhere else.
Since the links "Id" and "Title" by themselves don't have enough
information to let users know they're used to sort by ID or title, we
have to update them somehow. We could add a "Sort by:" prefix before the
list of links (and associate it with the `aria-labelledby` attribute);
however, we don't do this anywhere else and might look weird depending
on the screen size.
So we're simply adding "Sort by" before each link.
Now that we don't use the `wide_order_selector` partial anymore, we can
remove it alongside the styles for the `select-order` class.
JavaScript is used by about 98% of web users, so by testing without it
enabled, we're only testing that the application works for a very
reduced number of users.
We proceeded this way in the past because CONSUL started using Rails 4.2
and truncating the database between JavaScript tests with database
cleaner, which made these tests terribly slow.
When we upgraded to Rails 5.1 and introduced system tests, we started
using database transactions in JavaScript tests, making these tests much
faster. So now we can use JavaScript tests everywhere without critically
slowing down our test suite.
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.
