Ownerless projectiles remain on the screen forever

[Funatiker]

Sometimes enemies shoot projectiles while (?) dying. In that case, it might happen that a projectile remains on screen. It stops moving when the death-animation has finished but it won't disappear but stays animated (although not harmful anymore).

@WinterLicht is it possible that check_to_deactivate() (statesystem) activates dead enemies and makes them shoot projectiles after the death animation has been started?

Edit: I've written a bit of debug code:
debugcode.txt

It indicates that statesystem.py actually re-activates dead AIs:

$ python game.py
HELP I DIED 60
HELP I DIED 59
HELP I DIED 57
HELP I DIED 58
I am the statesystem and I am activating a dead ai. Really. Not kidding 58

I added of more line of print()-debugging and now I see that the AI sometimes tries to attack after dying.
