database gets corrupted if replication fails on re-login

[Sergey Gavrilov]

1. Login as user A
2. Wait auth cookie expired
3. Reload the app (goes to login form)
4. Login as user B
5. Interrupt server connection while loading mindset (replication fails)
6. Reload the app

Actual: "No root idea" error on load (like current user is still A).
Expected: login form opened.
