Symfony seems to almost always using namespaced Exception rather than default one.
This is useful:
- In order to do custom catch
- When using static analysis and you want to track some exception and exclude others

But the ConstraintViolationList was throwing the PHP OutOfBounds exception even if a namespaced one exists for Validator component. This PR is BC and change this.
