Fix code for HFID casting of strings that aren't UUIDs (#732)

* Fix code for HFID casting of strings that aren't UUIDs so user doesn't have to provide HFID directly if single value HFID.

* Fix linting issues.

* Fix card one from being double wrapped list.

* Update to not double wrap a list for a card one rel.

* Fixed typing error.

* Sessived code comments. Fixturized testing.
