Not able to fetch order if payment type is leasing

[Tasteful]

In the following row it defined that the payment type for leasing is LEASINGMANUAL

svea-sdk-dotnet/src/Svea.WebPay.SDK/CheckoutApi/PaymentType.cs

Line 105 in 4950d52

LEASINGMANUAL,

In the json-response for a leasing order we instead got the payment type as LEASING

This will end up in the following exception

Repro steps

1. Create order Checkout.CreateOrder(payload)-method.
2. Render html-snippet to the client.
3. Place an order with the LEASING payment type.
4. User will be redirected to the confirmation URL.
5. In the confirmation endpoint try to fetch the order Checkout.GetOrder(orderId)

Expected: Get the order from for the ckeckout to be able to validate the status on the order.
Actual: When the Checkout.GetOrder(orderId) should deserialize the response the above exception is thrown.
