RoutesParser does not invoke method extractControllerNameFrom in all cases

The VRaptor [documentation](http://www.vraptor.org/en/docs/components/#changing-default-uri) references that is possible to override the convention, but when is used the @Path annotation it's not invoking the method.

This is not the expected behavior.

if you use `@Path("/xx")`, `@Get("/xx")` or any other like this, VRaptor won't call extractControllerNameFrom

This is the method you should override:
