    machine: Handle new disconnection cases
    
    Now that we decided to keep the SPICE display connection open in
    collection mode in certain situations, we shouldn't rely on trying
    to disconnect the display solely based on the UI state change, because
    we would ignore the case when the machine is disconnected or paused
    but its UI is already in collection mode.
