Due to this error, user can't login to the Satellite using his/her Ldap account because Satellite will attempt to sync the users and groups after authenticating the user.

How reproducible:
The issue can be reproduced with just the internal authentication. The following steps assume that you have a freshly installed Satellite 6.6.

Steps to Reproduce:
1. In the web ui -> Administer -> User Groups. Create 4 user groups. We expecting the id of the groups are 1,2,3 and 4.

group1
group2
group3
group4

2. Make the Id of the default "Admin User" is 4.
3. In this case, id of the "Admin User" and group4 are conflict.
4. Add group1 as sub-group for group3.
5. Add group3 as sub-group for group4.
6. Add the default "Admin user" to group3 and submit.

Actual results:
Adding would cause a cycle!

Expected results:
Should be able to add the user to group3.
