If an operation is discarded during state transfer because it was already modified locally, the QueryInterceptor still propagates it to the index, leaving the index out of sync.

Sequence of events:

• T1: State Transfer starts
• T2: The EWI (EntryWrappingInterceptor) starts tracking all non-state-transfer operations
• T3: An entry is added locally
• T4: EWI stores the key
• T5: The same key arrives from State Transfer
• T6: QueryInterceptor indexes it (The QI is installed after EWI but indexing happens before storing the entry in the data container)
• T7: The entry operation is not committed in the data container since it was tracked before as DiscardPolicy {discardStateTransfer=true, discardXSiteStateTransfer=false}
• T8: The index and the data container differ, since the index applied the state transfer operation when the data container didn't
