user_id missing from message about federation roles

[Steve Martinelli]

In the token common provider, the call to _populate_roles_for_groups() is missing the user_id argument, and it is defaulted to None.

Thus, whenever a user is associated with a group that has no roles on either scoped project or domain, then the error message will always be: 'User None has no access to project %(project_id)s'
