Switching between `test_case_insecure` may cause weird behavior

The `user_id` is missing from the `test_case_user()` method. This is used when `test_case_insecure` is set to `True`. This should not impact production servers. This may be a super easy fix by adding `user_id` to the returned `user_info` object.

Search for the test_case_user() method and inspect the user_info object it returns when test_case_insecure is True. Confirm that user_id is absent in this path, add it to the returned object, and verify that the insecure test-case behavior now includes the identifier without affecting production behavior.
