- 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.

Support noticed that a number of exceptions, such as
"Encoding::CompatibilityError (incompatible character encodings: UTF-8 and
ASCII-8BIT)", failed to report to Sentry. The `rescue_from` in the
ApplicationController prevented these exceptions from being recorded.
This change ensures that these exceptions are properly captured.
