Sebastian Keller 79acae4176 dnd: Don't try to restore to parent location if parent got destroyed
The original parent of a dragged actor might have been destroyed after
the drag has been started. When the drag is canceled and _dragOrigParent
is set, the code is trying to get the current position and size of it
when restoring. With a destroyed parent this however would result in a
crash.

This could happen for example when starting a drag on a window preview
while the overview is hiding and then releasing it once the transition
is done.
