window: Postpone focusing until grab ended if uninteractable

Browse Source 
When GNOME Shell is in the overview, we don't want windows to steal
focus left and right, but once we leave the overview, we do want
whatever was mapped with "take_focus" to get focus. Do that, but after
the last grab was dismissed.
