    window: Check fullscreen status when window changes monitor
    
    For wayland meta_window_move_to_monitor sends a configure to the client
    without actually moving the window, yet and the
    meta_display_queue_check_fullscreen call won't detect any changes.
    Checking for fullscreen in meta_window_update_monitor fixes the problem
    because it is called whenever the window actually changed the monitor it
    is on.
