Subject: [PATCH] Don't process despawn if entity is in a chunk scheduled for
 unload

This won't happen anyways if the user has
"skip ticking for entities in chunks scheduled for unload" turned on,
but if they don't, protect from this instant killing the entity to
keep it vanilla in behavior

a player may teleport away, and trigger instant despawn
