swipeTracker: Reset before emitting 'end' and not after

If the actor is unmapped in the handler, the touch gesture will cancel.
Since we haven't reset the state yet, it will still work and will actually
cancel the gesture, so reset before that instead.

Fixes overview cancelling when trying to open it with a swipe.
