MDTranslator ISO to DCAT-US end-to-end test fixes

[jbrown-xentity]

User Story

In order to make sure base use cases are covered, data.gov admins want a complete end-to-end test fixed for ISO to DCAT-US.

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• GIVEN the development work is complete
  WHEN the tests are run for MDTranslator
  THEN any items that aren't mapping in our default/best case scenario then an error is thrown.

Background

Related to analysis performed by metadata experts: https://drive.google.com/drive/u/1/folders/120R3ORnEvF1QFG4IuWch43H8WELtajFA

Security Considerations (required)

None

Sketch

There is already an end-to-end test in place: https://github.com/GSA/mdTranslator/blob/master/test/translator/tc_iso19115_2_datagov_to_dcatus.rb
Some tests are commented out, and probably relate to what is in the spreadsheet.
Ideally we should take a copy of the spreadsheet and work through what is addressed, commit by commit.

This might involve cleaning up our real world example to make it an "ideal" example.
