    messageTray: use alignment rather than gravity to position the summary
    
    Actors in clutter are supposed to be re-allocated with
    Clutter.AllocationFlags.ABSOLUTE_ORIGIN_CHANGED if they move relative
    to the screen, even if they don't move relative to their parent.
    Currently this does not work correctly for actors inside containers
    with non-northwest gravity. This is probably a fixable bug, but
    gravity has messed up other things in the past too, so let's just not
    use it.
    
    This change ensures that summary trayicons are re-allocated when the
    summary animates, and is part of the fix for
    https://bugzilla.gnome.org/show_bug.cgi?id=635695
