=3974 per Persist (serialize) actor refs  with transport info

* The reason for the problem with NoSuchElementException in ClusterSharding was
  that actor references were not serialized with full address information. In
  certain fail over scenarios the references could not be resolved and therefore
  the ShardRegionTerminated did not match corresponding ShardRegionRegistered.
* Wrap serialization with transport information from defaultAddress
