Looks like we need to check not only that affNodes.containsAll(owners), but 
also that order of nodes in these collections (or at least first nodes, that 
are primaries) is the same.

> {{IgniteCacheAtomicProtocolTest.testPutReaderUpdate1}} and 
> {{IgniteCacheAtomicProtocolTest.testPutReaderUpdate2}} are flaky.
> In the {{#readerUpdateDhtFails}} method we blocks 
> {{GridDhtAtomicNearResponse}} messages and do put operation. Put should hangs 
> always, but sometimes it doesn't.
