AbstractEJBClientTestCase provides some convenience methods for starting and stopping servers, deploying and undeploying deployments, etc. Most test cases have been refactored to use this base class but a few were missed.

This issue will make sure that all test classes subclass the framework and use the common convenience methods of the existing AbstractEJBClientTestCase. This is in advance of the new EJB client test framework being introduced to make setting up the test environment simpler.
