> StoreScanner#next tries to ensure that the KVs are pulled from the heap in-order. The prevKV is used for this and is compared with the latest KV pulled from the heap. Since copyKV can be modified by ScanQueryMatcher, prevKV should track the KV pulled from the heap, and not copyKV. This is a one-line fix.
