This is public API and breaks the middlewares of existing apps. Since this also requires maintaining two different code paths for 12 and 13 I'm at the moment voting for reverting this change.

This fixes infinite loops that are caused whenever a user is about to solve a 2FA
challenge, but the provider app is disabled at the same time. Since the session
value usually indicates that the challenge needs to be solved before we grant access
we have to remove that value instead in this special case.
