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.
That's because `CDIProxies.unproxifyIfPossible` is prepared to unproxify CDI proxies. In your test, you are using javassist to generate the proxy. Is it possible to build this proxy with Weld api? Or you can create a mock of `TargetInstanceProxy`.
