We're using `eq` and `match_array` in most places, but there were a few
places where we were still checking each element is included in the
array. This is a bit dangerous, because the array could have duplicate
elements, and we wouldn't detect them with `include`.
Settings are stored in the database, and so any changes to the settings
done during the tests are automatically rolled back between one test and
the next one.
There were also a few places where we weren't using an `after` block but
changing the setting at the end of the test.
