Medical - Don't play *_medic anims at end

[PabstMirror]

User reported that when unarmed, rapidly bandaging themselves they got animation locked into a "holding an invisible gun" in a crouched pose.

Debugging, it seems to be that we're still playing ainvpknlmstpslaywrfldnon_medic when we start the 2nd treatment, so that gets saved and replayed again at the end. And without a fakegun, this seems to lock up the player.
