Allow using old ender pearl behavior & apply ender pearl exploit patch (#11524)
When enabled, ender pearls will not load chunks and will save to the world instead of the player.

Also changes the exploit config to be default false, as it only makes sense when legacy behavior is enabled.

Subject: [PATCH] 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.
