    Frontend-GNOME: don't push last seen message for each chat when disconnecting
    
    Each chat gets removed to release all resources when disconnecting the frontend
    from the engine. This triggered a chat switch for each removed chat. Then each
    chat switch triggered pushing the last seen message to the remote engine.
