[w3c/browser-payment-api] Fix constructor handling of shippingType (#452)

If shippingType is provided, it will always be a valid shipping type, now that we are using an enum (as of 7e9a3323ac7ed932597fe4b3963331f9fa883041). But we also need to correctly handle the case where it is not provided, or where requestShipping is false, in which case it should be null.
