FIX: Reset 'filter' query parameter when clicking on a nav-item (PR #10299)

Usually, this would have been implemented using resetController, but because we do not use link-to component for linking, that method is not called.


I assume it’s really hard to make a test for this? If it isn’t I would like one.

I could not write a test because when click() is executed on a nav-pill it somehow breaks out of QUnit. Not really sure what’s wrong.
