altTab: remove erroneous/superflous pick

AltTabPopup was calling global.stage.get_actor_at_pos() "to force a
stage relayout", but that function does not actually have that effect.
It was also occasionally causing Clutter warnings (possibly due to a
clutter pick-buffer-caching bug?). So just remove the call.
