When trying to deploy an application with clustered singleton MDB delivery, we see this error:
"WFLYCTL0412: Required services that are not installed:" => ["org.wildfly.ejb3.clustered.singleton"],"WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.deployment.unit.\"messaging-clustering-singleton.war\".clustered.singleton.dependency is missing [org.wildfly.ejb3.clustered.singleton]"]}}}

The clustered singleton service is not being installed with the expected name.
