protected function ComputedItemList::ensurePopulated in Salesforce Suite 8.3

Makes sure that the item list is never empty.

For 'normal' fields that use database storage the field item list is initially empty, but since this is a computed field this always has a value. Make sure the item list is always populated, so this field is not skipped for rendering in EntityViewDisplay and friends.

@todo This will no longer be necessary once #2392845 is fixed.
