Remove last bit of chunk exists region file fix
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] Improve Minecraft Hopper Performance
Removes unnecessary extra calls to .update() that are very expensive
Also reset cooldown each hopper tick that a hopper is full.
Also don't constantly clone ItemStacks without merit
