SdrUndoDelObj: one more manual swap out call

This thing seems a good optimization to me, but
it would be good to hide all of this swapping thing
inside GraphicObject class, to make our code more
robust (e.g. no image loss because of missing
manual swap in / swap out call).
Auto swapping mechanism will take care of that, anyway.
