99 Problems but Pokemon Go ain't one (Rails request spec dependent failures, wrong SQL generated)

The Problem

We currently face a problem when a request spec fails (typo or other exception) it affects other request specs which actually should be unaffected. The problem is we use many gems so I tried to create a minimal reproduction app (without success, https://github.com/tak1n/reproduction)

The problem in detail:

We have a request spec where we need to login a user. For user authentication we use devise and therefore we use Warden::Test::Helpers to log in users in request specs. Devise automatically updates some user related attributes when a user logs in (last_sign_in_at, last_sign_in_ip etc..).

The problem here is that when it tries to save the user for doing this changes the end result is a INSERT INTO user instead of a UPDATE user and therefore it crashes.
