    MetaWindowActor: fix reference counting issue
    
    We need to use g_signal_connect_object(), rather than g_signal_connect(),
    because the window actor can be destroyed before the window emits
    the final notify::appears-focused inside unmanage, if the plugin
    decides that it doesn't want to animate the destruction (which
    happens with dialogs and the default plugin)
