core/rawdb: improve state scheme checking (#28724) 

This pull request improves the condition to check if path state scheme is in use. 

Originally, root node presence was used as the indicator if path scheme is used or not. However due to fact that root node will be deleted during the initial snap sync, this condition is no longer useful.

If PersistentStateID is present, it shows that we've already configured for path scheme.
