Guard updateLayer for deleted windows

Browse source 
When a window is deleted it all "set" operations should no-op.

As for the bug specifically, we have an effect that keeps the desktop
alive. If a user calls showDesktop not only do we not update the
stacking order, we also call updateLayer when the client closes this is
after the window is in the deleted state.
