bug(users): Mark users as verified if user comes from SSO

- Currently we are not marking users as verified if they use SSO to login.
- But if there is only SSO to login, then they won't be able to verify their email unless they come from the accept invite email.
- Instead, we will mark users coming from SSO as verified.
