Iqss/7349 2 improve related pub citation entry

[qqmyers]

What this PR does / why we need it: Per issue #7349, Google does not like aspects of how we send related publication info. Specifically, the citation key (where we record related pubs) has to be text or a CreativeWork object. For a CreativeWork object, Google expects a name or URL, and we weren't sending either. This PR adds a 'url' if an identifier URL is provided and moves our 'text' entry (the Citation child field) to 'name' which addresses the case where a URL isn't provided. (Nominally the Citation field is neither the name of the CreativeWork or its text contents, but there doesn't appear to be a better option and the Citation should at least include the title along with author/publication info.

Special notes for your reviewer: This is one of ~4 PRs to close the issue

FWIW: For authors, we've added methods that try to provide a URL form for most/all identifier types allowed - something similar could probably be done here to also capture cases where someone has entered type 'doi' and the numeric identifier and the id itself but no url. Currently entries in those fields are not used in creating the schema.org output.

We are also currently sending the URL as an '@id' and as 'identifier', so with the change here we now send the url 3 times (adding a 'url' key). The other two could still be useful so I've left them for now. Conversely, I've removed the 'text' key given that it is not really a valid use (our content doesn't match the definition). Both just judgement calls.

Suggestions on how to test this: Just verify the unit tests run. Can confirm manually by adding a related publication with a Citation and or URL fields and verifying that they show up as the 'url' and 'name'.
