Assigning a role that does not exist: error synchronizing: clusterrole.rbac.authorization.k8s.io "rolename" not found

Issue

If a role that does not exist in OpenShift is assigned to a user, the operation is completed successfully, no errors are raised from the command line but some leftover items are stored in rbac metadata.
In addition, the atomic-openshift-master-api service is reporting some errors about this role permanently:
