Don't delay chunk unloads during entity ticking

Browse Source 
Leaf informed me this could cause ordering issues.

So, the risk if this occurring is lowered now anyways, but if an
entity causes a sync chunk load, it could process an unload...

We will tackle the problem better in a future commit

Also fixed another async-chunks=false issue
