Giovanni Campagna 15063ef3d5 WindowManager: clean up scale_y when overwrite the map animation 
If we overwrite a map animation (for example because the actor is now destroyed),
we need to complete it first, otherwise it starts off from a random
middle point. This is the same treatment opacity gets for normal windows.
