Remove last bit of chunk exists region file fix

Browse Source 
CraftBukkit removed their implementation that caused this issue,
switching to Mojang's implementation which doesn't appear to share it. I
already removed the important bit in the last upstream merge, this is
just unused and unnecessary now. So we remove it.

Subject: [PATCH] Use Optimized Collections
Swap out CraftBukkit LongObjectHashMap with Long2ObjectOpenHashMap
Swap out Integer key HashMap for a Int2ObjectOpenHashMap For ChunkProviderServer
Amaranth, the creator of LongObjectHashMap, tested it vs fastutil and determined fastutil to be 3x faster
and could not create anything faster than fastutil.
These collections are super fast as seen
