BusDeploymentAspect creates CXF DefaultBus using wrong class loader

Cloned from https://github.com/wildfly-extras/wildfly-camel/issues/2670

org.jboss.wsf.stack.cxf.deployment.aspect.BusDeploymentAspect.start()` [1] is probably triggered by some WS annotation. It sets a class loader of `org.jboss.ws.jaxws-client` which is then effective for all calls to `org.apache.cxf.bus.extension.ExtensionManagerImpl.getBean[s]OfType()` which in turn returns the jboss-ws implementation of `HttpDestinationFactory` intead of ours. This turns out to be a problem for CXF RS tests using https endpoints. A stack trace like this occurs:

`CXFRSBasicSecureProducerIntegrationTest` from https://github.com/wildfly-extras/wildfly-camel/pull/2661 demonstrates the issue, but only if it is run after e.g. `CXFWSSecureProducerIntegrationTest`
