Stanilovsky Evgeny commented on IGNITE-584:
-------------------------------------------

we need to set _keepBinary=false_ on _onEntryUpdated_ for proper unwrap non _Externalizable_ class _CollocatedSetItemKey_ and further _if (key0 instanceof SetItemKey)_ check, otherwise we need to implement _CollocatedSetItemKey_  as _Externalizable_ too and replace from registerPredefinedType.

> Consistent results on topology changes was implemented for sql queries, but looks like it still does not work for scan queries.
> This affects 'cache set' tests since set uses scan query for set iteration (to be unmuted on TC): 
> GridCacheSetAbstractSelfTest testNodeJoinsAndLeaves and testNodeJoinsAndLeavesCollocated; 
> Also see todos here GridCacheSetFailoverAbstractSelfTest
