Describe the bug

User (that email domain matches domain already used in any organizations) without any organization assigned gets organization claim in access token witch is in my opinion very very unwanted situation.
Issue occurs when we create user with email domain that is assigned to organization. Then even so user is not a part of the organization gets organization claim in access token. (user has no organization and organization has no users).
Wrong claim is assigned only using client with real application - evaluation tool for that particular client works correctly.

nightly
