Guard against prototype extended arrays (#769)

Frameworks like Ember extend the array type with
additional properties. Although they can be
disabled, it would remove some helpful
features. In the case, the iteration through the
additional properties by the execute validator
code can result in `undefined` being passed as the
third argument.

This commit guards against that case.
