Fix build for !12300.

- The `/users` and `/users/:id` APIs are now accessible without
  authentication (!12445), and so scopes are not relevant for these endpoints.

- Previously, we were testing our scope declaration against these two methods.
  This commit moves these tests to other `GET` user endpoints which still
  require authentication.
