workspace: Unbreak reposition animation

Commit 1ea22a5281 broke the window reposition animation when it
based the ::size-changed signal on the layout manager's bounding box
instead of the MetaWindow::size-changed signal.

That's happening because of the combination of:

  1. we adjust to window size changes immediately without animations
  2. closing a window triggers a change to a 0x0 bounding box which
     is not treated as a size change

Fix this by addressing the 2nd factor, and don't treat a change to
a 0x0 bounding box as size change.
