[bug] Redirect appears to not work for `/oauth/authorize`

[Cictrone]

Describe the bug
It seems that the redirect on/oauth/authorize does not work anymore leading to a very weird log in flow. The sign in works but you just need to manually redirect yourself to tavern once you hit this step.

To Reproduce
Steps to reproduce the behavior:

1. Wipe all Tavern Cookies.
2. Log into Tavern via the OAuth sign-in flow.
3. See after sign-in you are sent back to /oauth/authorize?state=<stuff> and no redirect occurs
4. See Auth Cookies were set but no redirect

Expected behavior
To be redirected back to the Tavern UI after login.
