WFLY-3260 Fix WSTestCase
- remove unnecessary classes
ServletContext.getVirtualServerName always returns "localhost"

I experimented with the new getVirtualServerName method introduced for interface ServletContext in servlet spec 3.1. The JavaDoc states: Returns the primary name of the virtual host on which this context is deployed. The name may or may not be a valid host name.

However Wildfly always seems to return "localhost" instead of the virtual host name specified in XML configuration files. My host config in standalone.xml looks like this: <host name="default-host" alias="www.sample.com">. I expected that getVirtualServerName returns "default-host" in this case. 

getVirtualServerName is implemented like this: "return deployment.getDeploymentInfo().getHostName();". However DeploymentInfo.setHostName is never called during startup. 

If I did not misunderstand what getVirtualServerName is supposed to deliver, something similar to my proposed patch should fix the problem. Sorry, I only looked at Wildfly source code for the first time today in a debugger and was unable to verify if my proposed patch compiles :( Hope a more experienced developer can have a quick look.
[[WFLY-3493] Do not remove a JMS resource with deployed dependencies

Ensure that there is a dependency between the JMS resource service
(JMSQueueService and JMSTopicService) and the BinderService for their
JNDI bindings so that if the resource is removed, the missing dependency
is detected.

Add recovering of the JMSQueue and JMSTopic services in the :remove
operations by replaying the runtime part of their corresponding :add
operations.
