Fixed issue 733 Getting wrong path when trying to use logic forwardTo

The getFilteredControllerBaseName method was created to filter baseName that may be using proxified controller base name. Without this filter, extractControllerFromName wouldn't be able to extract Controller suffix.
Hello @lucascs.
I'm trying to figure out how to effectively test it but having no success :(
When verifying as you suggested, tests are failing. So I realize that I can't invoke redirectTo or forwardTo using a proxified controller through proxifier.proxify(RandomController.class).

When debugging, I saw that our controller is an instance of something similar to ExampleController$Proxy$__$$_Weld****. And such an instance is created by invoking beanManager.getContext inside InstantiateObserver.

Do you think it's better to keep talking about it at caelum-vraptor-dev google group? Because I'm having doubts about the source code ;)

Thanks
