Subject: [PATCH] api_docs: Add check for extra `additionalProperties` in
 return vals.

Adds a check for `additionalProperties: true` when there are no
properties listed in the schema.

This currently only happens in one place, but will be helpful for
deduplicating text between the `register-queue` and `get-events`
endpoints.
