LibOverride: fix bad ID relationships handling during resync. 

Purely local IDs would not always be used as proper barriers when
generating override hierarchy data, leading to imporperly trying to
resync override IDs from other hierarchies, which would break/cause
issues in case they would be duplicate overrides of the same linked
data.

Reported by Pablo from Sprite team, thanks.
