Correctly focus fuzzy-finder/event-palette when triggered while other is showing

When canceling the fuzzy finder or event palette, we should only focus the root view / previous element if the mini editor is still focused. Otherwise, it was a change of focus elsewhere that caused us to be cancelled, and we don't want to interfere with that focus change.
