Remove old filter test (#29963)

This wasn't testing what it thought it was testing because the primary
filters aren't present at all after selecting a secondary filter that's
not compatible with them, so it was just asserting that some other filter
(which had the same index as the old one) was disabled. It breaks if
the primary filters get reordered.
