Description of problem:
Unable to remove Ansible Roles from host group in Foreman UI.

Steps to Reproduce:
1. Import ansible roles. (Configure > Roles > import)
2. Go to, Configure > Host Group > Create Host Group
3. Go to Ansible Roles tab.
4. Assign Ansible roles to hostgroup. Click submit.
5. Edit the host group created earlier.
6. Remove Ansible roles from host group. Click submit.
7. Again click on host group and go to Ansible roles tab.

Actual results:
- Ansible roles are listed in "Assigned Ansible Roles" even after removing them.

Expected results:
- Ansible roles shouldn't be listed in "Assigned Ansible Roles" section after removing them.

Additional info:

- In /var/log/foreman/production.log I can see the assignment/removal of
Ansible role is happening, it seems like it's only issue with UI.

- When Ansible role is assigned to hostgroup.
