Title: Fix FormRequest's error message handling

This change will allow the use of MessageBag's helper methods such as `first()` on a FormRequest's failed validation response... eg. `$errors->first('field_name')`

This functionality already existed in legacy, 4.2, validation. Therefore, this change brings forth a bit of consistency between the two.
