Chained structs *may* contain objects which means deserialization may need an ObjectIdResolver. However, in practice, we never need to send chained structs from the server to the client that contain objects for a valid command. The one upcoming need for chained server->client structs is to serialize limit structs. Because limit structs never need objects, we provide a dummy implementation of the ObjectIdResolver which always yields an error. An analogous change is done for ObjectIdProvider. These classes will be used in a follow-up CL.
