function configuration_check_user_role in Configuration Management 7

User roles are unique in that the name of the config and the name of the role are the same. If you change the name of the role, you are effectively creating a new configuration item. For that reason, we have to check to see what roles are no longer existent in the activestore, and mark those as changed.
