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.
You're welcome :) I didn't suggest the fix here because we need this PR merged to release RC2, so I've provided a fast fix instead. Thanks a lot for your contribution.
