Order change: Fix crash if addon has hidden_if_item_available (Z#23236380) (#6357)

* Fix crash in rebooking if addon has hidden_if_item_available
* Move get_grouped_items into its own file and rename to prepare_item_list_for_shop
  (but keep a reference under original name for plugin compatibility)
* Make Item[Variation].unavailability_reason helper functions next to get_grouped_items
* Use current_unavailability_reason attribute instead of unavailability_reason()
* Add test case for:
  Order has product with addon 1; Addon 1 is hidden if Addon 2 is available; When order is changed, Addon 1 should not be removable
* Fix special case if addon product is now set to require a voucher (vouchers for addons are not supported)
