Title: Improved previous fix for ZF2-558.  

Previous fix made implicit assumptio...ns that could cause issues in subclasses of Element\[Select|MultiCheckbox]. This fix dispenses with those assumptions so subclasses that override getValidator() and attach validators that are neither InArray or Explode won't break. For instance, [DoctrineORMModule\Form\Element\DoctrineEntity](https://github.com/doctrine/DoctrineORMModule/blob/master/src/DoctrineORMModule/Form/Element/DoctrineEntity.php) was broken by the original fix (294a7d18a832ce5eb297b43832c2b67db77fb425)
