[Bugfix] quick changing of target slot restarts animation of hiding

Take weapon from automatic slot into hands. Press key to change slot to pistol's one. Then change slot to knife's one without waiting for changing completed. Hiding animation will be restarted. You can never change slot while you repeats such actions.
