fix(order): answer 404 instead of 500 for a missing order

findOne and findOneByUuid mapped order.cart before checking that the order
exists, and the service's findOneByUuid did the same, so a missing order
threw a TypeError: GET /orders/:uuid/cart, add-product, remove-product,
generate-invoice and generate-delivery-note answered 500.

The service's findOneByUuid now returns null for a missing order, and each
caller handles it: the controllers answer 404, sendInvoice and
sendDeliveryNote throw a NotFoundError.
