Refresh ProjectileSource for projectiles

Makes sure the value returned by Projectile#getShooter in
the API matches the owner UUID specified in the entity nbt.
Previously, after the entity reloaded, Projectile#getShooter
would return null, while the entity still had an owner.

Also fixes setting the shooter/owner to null actually
clearing the owner.
