@WebEndpoint name not considered when building up webservicerefs

When building up webservice refs for a provided Service class, we currently look for 'getXYZ' methods with proper return type and select the first one with proper signature (for instance supporting WebServiceFeature).
A user provided Service class could possibly have multiple getPortName methods returning the same service endpoint interface, but actually using different wsdl ports. That is possible when different @WebEndpoint annotations are specified. In such a scenario, if the user has also specified the required port QName in the webserviceref metadata (port-component-ref block, for instance in jboss-web.xml), we need to select the right method my matching the name of the @WebEndpoint annotation.
