Get Wrapped Viewhandler (Avoids java.lang.InstantiationException: org.jboss.weld.module.jsf.ConversationAwareViewHandler)

[volosied]

Due to JSF-CDI changes, org.jboss.weld.module.jsf.ConversationAwareViewHandler is the default viewhandler.

https://github.com/weld/core/blob/master/modules/jsf/src/main/java/org/jboss/weld/module/jsf/ConversationAwareViewHandler.java

During the tests, JSFTestUtil tries to instantiate this class, but fails because it needs arguments in constructor.

Since ConversationAwareViewHandler extends ViewHandlerWrapper, we can cast it as ViewHandlerWrapper and get our JSF ViewHandler instead (com.sun.faces.application.view.MultiViewHandler).

As always, please test and verify :)
