Bug 1426957

Description of problem:
User group assigned to particular role(s) seem to receive their assigned permissions, but the roles to reflect those permission are not seen in the webui.

Steps to Reproduce:
1. Create an authentication source - ensure 'Automatically create accounts in Satellite' is set
2. Create a role with some permissions
3. Create a user group, assign to this the role from step 2. Assign an AD group to this too.
4. Login as a user who is a member of that AD group.
5. The account is created (the user does not have proper permissions until foreman-rake ldap:refresh_usergroups is run)
6. When viewing the user Settings -> Users, note that the Role tab does not reflect the roles which have granted this user access.

Actual results:
User is given role, but the role is not seen in the webui.

Expected results:
Expect that the roles a user has been given can be seen if they have the permission to view roles.

Additional info:
User's cannot see their own roles as well in <username> > My Account > Roles - this page is blank. But with a normal locally created user with the same permissions, this page is populated.
