[geary] Disconnect from UI/Engine signals when closing app

    Disconnect from UI/Engine signals when closing app
    
    This prevents a lot of extraneous (and often erroring) operations
    when Geary closes, particularly due to the conversation and folder
    list selections changing as items are removed.
