clutter/actor: Don't emit focus signals during destruction

Browse Source 
We rightfully unset the stage focus when the focus actor is destroyed,
which in turns results in the ClutterActor::-key-focus-out signal being
emitted on an actor that is no longer fully valid.

Avoid that emission, so consumers don't have to deal with half-disposed
actors in their handler.
