soap:address rewrite does not consider wsdlLocation in SEI @WebService

There's a bug in the MetadataBuilder that does not use the @WebService(wsdlLocation=...) data from the service endpoint interface when the information is not available in the annotation on the endpoint implementation. The retrieved data is used for the wsdl soap:address rewrite (only), which is hence not working properly when the only wsdlLocation data provided is in the SEI (not in the impl, not in a deployment descriptor).
