Fix puller not being improperly unset on PullableComponent while being unpulled.
When unpulled, the pullableComp has its puller field set to null after the message signifying the pulling has stopped
has been sent. Since the component has a field to determine whether its owner is being pulled which is determined by
the puller field, systems listening on the event would think that the owner of the component was still being pulled.
