In commit baaec3a29 we started using the JavaScript driver in tests
dealing with the user menu, and made all tests pass.
However, we didn't update some officing tests that were also passing
when there was a bug in the code. That's because now that these tests
use a JavaScript driver, the link to "Polling officers" is never present
before pressing the "Menu" item. So tests checking the link isn't
present when loading the page always pass.
