Calls to manifest, without a referrer, affect session history and back redirect navigation #4649

Describe the Bug

When logging in with OIDC the login is successful, but the browser is then redirected to /manifest.json which is confusing, since the user should be redirected to the normal Booktack interface. But after removing /manifest.json from the url to open booktack normally the user is logged in.

Steps to Reproduce

1. Make sure you are signed out
2. Login using OIDC
3. Get redirected to /manifest.json

Expected Behaviour

The normal landing page should be open on the / url.

Screenshots or Additional Context

My OIDC callback is configured to `/oidc/callback
