Fixup content_export_complete LiveEvent metadata/body

Fixes: QUIZ-1478

Move the context_type/id to the attributes
Tack on amended_context to the payload

Test-Plan:
  o With live events set up for local testing
    - Assert that the quiz_export_complete event looks right
      - It should contain uuid/root_account_id/and everything else
        in the attributes
      - It should not contain context_type/id in the body
