AssertionError "rev is None" in fuzzy_find_documents() after feat/rfc deployment

[jennifer-richards]

Describe the issue

After deploying v12.0.0, a call to document_pdfized() led to a failed assertion in fuzzy_find_documents()

The offending parameters were {'name': 'rfc4231', 'rev': '02'}

Traceback in a screenshot here because I don't have a better way to copy/paste at the moment

I think the log.assertion was a mistake - this code deals with strings provided directly in urls which may be nonsense, and it should just not find anything matching the nonsense.
