Cleanup more follower leaks (#20902)

Browse Source 
* Cleanup more follower leaks

Rather than check stop everywhere we'll just check it on start and cleanup the old following. If someone were already following and followed something new the FollowedComponent would never get cleaned up and would never have its ref to the entity removed.

* Don't cause archetype changes
