[Redesign] Improve showing "Clear report" button

[mhansma96]

The Clear Report button is now shown when you add a value to a criteria on the "Audit Sample" page. But what if we add other fields like the version, the title or target, shouldn't the button appear then as well?

I think we'd like this, but didn't do it previously because we didn't find a “clean” way to do it. If you do find a way, feel free to make this work! (cc @nitedog)
