Marcel de Rooy 75e11d85d0 Bug 28786: (QA follow-up) Check the returned CSRF token
We're doing this in the registering stage and at disabling.

Test plan:
Ënable two-factor auth but logout/login on another tab. You should
get the Wrong CSRF token when submitting.
Do similar thing while disabling.
Verify that you can register / disable when in the same session.
