template: Move admin_user_group_list template to settings folder.

Moved `admin_user_group_list` template to `/templates/settings/` folder
as earlier, it was inaccurately placed within the `/templates` folder
and should have been within the `/templates/settings` folder.
Also modified the node tests to reflect the new changes.
