The Weld Arquillian embedded adapter should not load classes that are excluded in beans.xml

In some use cases, like the Camel CDI extension, some classes are excluded in the beans.xml and may not be in the class path. In that case, that leads to having a ClassNotFoundException thrown by the adapter that tries to load the bean classes regardless the exclusions from the bean archive descriptor:
