Doc: JSF/ExceptionControl integration redirect example

http://deltaspike.apache.org/documentation/jsf.html#_intergration_with_exception_control_since_0_6 , Redirect example:

• FacesContext.getCurrentInstance().setResponseComplete(); is incorrect, the method on FacesContext is called just responseComplete()
• the example should maybe show DS's own ViewNavigationHandler since it performs the same operation as is demonstrated in the example
