Unassign shipping address on CheckoutDeliveryMethodUpdate from C&C

[tomaszszymanski129]

I want to merge this change because it fixes behavior of C&C with checkoutShippingMethodUpdate.

• Switching to a collection point with WarehouseClickAndCollectOption.DISABLED is now forbidden and will raise ValidationError.
• Switching from C&C to a standard delivery method now removes the shipping address from the checkout (it used to stay with the warehouse address).
• Switching the delivery method to none (without passing deliveryMethodId) now removes the checkout address if there was C&C previously selected.
• Switching from C&C LOCAL_STOCK to ALL_WAREHOUSES now works - shipping address updates to the new collection point.
• Warehouse is now validated by the variants from checkout.
