Title: FIX: sanity check for wrong replication tree 

If channel site for SE cannot be obtained, replication tree is wrong. This fix adds a sanity check comparing requested TargetSEs set with obtained one. If there is a difference, S_ERROR is returned from ```StrategyHandler.determineReplicationTree```.

This should also land in the intergation branch.
