url endpoint to track unauthenticated users before redirecting to final url
Cleanup

- Conformed the component name for comments to `wpcore` as now used elsewhere.
- Added some spacing and comments around the identity redirect, as well as a redirect for the negative case when looking up the user info.
- Fixed a notice when no tests are configured. Note @okredo about the expected type here.
