Both pairs are used in the tolua_game.pkg as if overloading functions. Since their fingerprints are identical, user cannot really select one over another (nor even to really see that there's two copies). Not sure which pair lua ends using, though the comments hint that it uses first one (as listed) methods that matches, i.e., the api_find_action_by_name() / api_find_action(). But that doesn't really matter. We can still remove either, and the remaining pair will provide functionality identical to old one even if the removed pair was in use.
