Updated Orders API

The rules for returning the id value when creating an order via API/orders for stores with consecutiveOrderIds enabled have changed.
Now the internal id value is passed to the consecutiveOrderIds in the id field instead of "-1" value. Thus:
If the new number format of the order IDs is enabled in the store, then Ecwid will pass order ID value in the orderid field.
If the consecutive old number format of the order IDs is enabled in the store, then Ecwid will send a response with the internal order ID value in the id field.
