    MetaWindow: don't set focus to unmanaged window
    
    Closing the last window causes the no-focus window to gain
    focus, which causes mutter to unfocus the just closed window,
    and that crashes. As focusing a window that is about to be
    destroyed does not make sense, avoid a crash in this case.
    
    Note: this is probably a reference counting bug in MetaWayland
    actually.
