The current 2-factor authentication method registration flow requires
email verification for both initial 2FA registration, and 2FA
re-registration even if the user is already logged in with 2FA.
This change removes email ID verification for users who are already
logged in with 2-factor authentication. Users who have only completed
first factor authentication (password) are still required to complete
email ID verification.
