ISPN-2846 OperationsDuringStateTransferTest fails if run on non-tx cache

NonTxDistributionInterceptor fetches remotely the value before executing a write command if the transfer of the key is in progress and the key is not available in the local data container. If the remote fetch returns null a local lookup is reattempted.

Please integrate in master and 5.2.x (t_2846_52).
