ISPN-3830 Conditional Operation can fail erroneously during ST

Throw the OutdatedTopologyException even if the command had failed locally.

I can't put a point on the next line, but it seems that key may not be owned by cache2 every single time.  Should we not create a MagicKey while we are still blocking the topology update so it guaratees cache2 is an owner?
