Note that in order to simplify the component tests (which for some
reason seem to be whitespace-sensitive), we have to omit whitespace
characters inside the `<option>` tags.
Also note we're simplifying the test with a missing language name; since
a component test doesn't involve a whole request, we don't need a
complex setup (I'm not sure we even need it in system tests).
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.
