Since 2.7.8 I got a BC-Break Error

Catchable Fatal Error: Argument 1 passed to Symfony\Component\Form\Extension\Core\Type\ChoiceType::normalizeLegacyChoices() must be of the type array, null given

normalizeLegacyChoices work only with array, so if choices not an array, just don't try to normlize.
