curies fail to roudtrip correctly

[tgbugs]

Curies to a full iri like definition: <http://purl.obolibrary.org/obo/IAO_0000115> fail to resolve correctly.
This url resolves and the PAXRAT: curie is clearly visible as part of the record. However when trying to use the curie directly SciGraph fails. URL escaping the colon also fails.

A related issue (prompting the title change), which is not so much a scigraph problem as a client problem, is that scigraph will shorten iris to curies that have slashes in the suffix (which is good), but if that curie is passed back into an {id} endpoint it will barf on the slashes in the suffix.
