mod_rest: Remove manual reference expansion in schema
This hack was originally added to reduce the number of definitions of
common attributes (type, to, from etc) and payloads (e.g. delay). This
predated pointers and references, and until now was needed because
parsing picked out the correct stanza kind from the schema, which broke
internal references.
Removing this hack paves the way for allowing the schema to be
configured or customized more easily.
