Users existing only on social auth (e.g. Keycloak) can not be added to organizations or projects
I've just successfully set up GlitchTip to be able to login via a Keycloak backend. However after logging in with such a user, it's not added to any organizations and instead GlitchTip recommends creating one. When clicking that button I get a message that "registration is disabled" which, yes, it is, but that should probably not prevent me from making an organization. At the very least it would be great to be able to add this user to an existing organization or project as an admin but this user doesn't show up anywhere for the admin.
