Fix many issues with dupe uuid resolve patch

Browse Source 
This was not applied correctly, and would completely blow up chunk entity
registration if this feature was turned off....

Additionally, change how the entities are removed to be more consistent with other code.

Surface some of the logs indicating there is a problem as we are having so many issues with
entities that we don't need to be surpressing logs like that.
