Shave spec/features/issues/filtered_search/dropdown_label_spec.rb from 10 minutes to 1.5 minutes

- Don't use `sleep` (most of the time was wasted by that)
- Expect some elements to be visible instead: capybara is smart enough
  to retry a few times if it cannot find an element
- See
  https://github.com/teamcapybara/capybara#asynchronous-javascript-ajax-and-friends
- Don't create unneccessary DB records
- Group some examples together to shave some setup time (where it makes
  sense)
