    windowManager: Fix a warning
    
    The destroy effect currently relies on a monkey-patched property
    added from the map effect. However on X11 it is possible that we
    did no map animation for a window that is destroyed when the shell
    was restarted or had taken over from another WM. Just use the real
    MetaWindow property to avoid a warning in that case.
