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.
