Some poms hardcode the org.wildfly maven groupId in references to internal artifacts

When declaring dependencies and other references to artifacts produced by the wildfly full build, the ${project.groupId} expression must be used instead of hardcoded "org.wildfly". This makes it possible to quickly change GAVs to org.jboss.eap by simply focusing on each pom's groupId declaration and ignoring dependency elements etc.

A few mistakes in this area have crept in during WF 13 work.
