MODE-2129 Fixed the deployment of the CMIS webapp inside EAP. 

The solution was to avoid using the default EAP WS stack (which uses CXF) since the CMIS webapp already has pre-packaged the RI jars.
In addition, reverted the changes from https://issues.jboss.org/browse/MODE-1913 since not using the default EAP WS stack fixes the restart issue as well.
