Hopefully will (f)ix #1280...
I'm suspicious that Citizens isn't calling things in the same order and causes the current
chunk to not be set, which then bugs removals. Though this doesn't make any sense to me,
so this likely won't fix it...
But if the isAddedToChunk is true, we really should be returning a chunk anyways if its loaded.
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
