Update tests to support corrected JSON Schema Generation PR (#380)

* Correct field and flag enumerations in JSON schemas.

Previously in #360, @kylelaker reported a needed
improvement to fix a regression for usnistgov/OSCAL#1773. While I had
been completing testing in #360 and properly expanding test coverage to
address how we handle enumerations based on allow-other and target
attributes for field and flag elements in Metaschema (both act similarly
but subtly different with more scenarios for field), I observed my test data
instances needed further correction in a way that cannot be address in the
PR by Kyle. This merges the changes from the commit reffed by the URL
below, adds my enhancement, tests, and all examples that helped me
uncover missing code.
