[PUI] Logout Fixes (#6318)

* Refactor method to extract token from request

* Reimplement error-report API endpoint

- Removed in previous commit - b8b3dfc90e
- Adds unit tests to ensure it doesn't happen again

* Adds custom logout view for API

- Ensure correct token gets deleted
- Our new custom token setup is incompatible with default dj-rest-auth
