Title: Fix 139: Broken `sf` (Symfony) rule

This **breaks compatibility** in my opinion, since people who are currently using this rule (compatible with `Symfony\Validator` < 2.1) will start to have problems; even though for *stable* versions of the `Symfony\Validator` this rule is not working at all (as noted on #139).
