Fix for ALF-786: WCM Cluster / Lucene: Searching in staging returns duplicate entries (when concurrently submtting)

- fixed duplication arising from indexing 0-1 and 0-2 against the index for near simultaneous snapshots 
- tracking has not been modified nor has index rebuild - the latest index info from the AVM index is definitive and complete - we do not have to do additional work as we do for DM
