[gnome-shell] Wanda: remove unnecessary destroy signal connection

    Wanda: remove unnecessary destroy signal connection
    
    'destroy' is emitted before the actor is unmapped during destruction, so
    notify::mapped would emit an exception. Since unmapping is guaranteed,
    the 'destroy' signal is unnecessary.
