--------------------------------------------------------------------

Root cause is identified: incorrect merge of IGNITE-6663 - it pass filter incorrectly, so
the same PK could be returned more than once if there are backups. 

See relevant TODO in {{H2TreeIndex.find}} method.

> Affected tests:

> {{IgniteCacheCrossCacheJoinRandomTest}}
> All tests failed for the same reason: {{expected=X, actual=2*X}}. Looks like we return
too much results in some cases.
