No invoiceId on shipped order

[JohanFriedrichsen]

According to the documentation for /api/v3/SalesOrders/{type}/{orderId} the financialInformation should contain an invoiceId for the invoice created for the order. However, we don't get that information using v3 (invoiceId, invoiceDate or duedate).

Getting the same order using v1/v2 produces the information under the shipping section.
