Fix returning tuples of lists of arrays from RPCs 

When serialising a list of objects `_send_rpc_value` makes a copy of the
upcoming tags to pass repeatedly to the recursive call. Then uses
`_skip_rpc_value` to skip over the tags that should have been processed.
This didn't handle numpy arrays so, after processing a list of arrays it
got out of sync and failed.
