AcmeOrderInfo is missing url in some cases

[sliemeobn]

After calling finalize, the order information passed back does not contain a url.

Eg:

let (privateKey, _, finalized) = try await acme.orders.finalizeWithRsa(order: order, domains: [domain])
let refreshed = try await acme.orders.get(url: finalized.url!) //url is not set

Also, acme.orders.get(url:) and acme.orders.refresh(&order) do not seem to include the url in their response.

That means that one cannot write a loop like this ATM:

let (privateKey, _, finalized) = try await acme.orders.finalizeWithRsa(order: order, domains: [domain])

var orderForDownload = finalized

while orderForDownload.status == .processing {
    try await Task.sleep(for: .seconds(1))
    try await acme.orders.refresh(&orderForDownload) //this will fail
    // as a work-around the url of the original order data must be used 
    // orderForDownload = try await acme.orders.get(url: order.url!)
}
