Quickpay: implement checking if order id is in use before setting form params
When generating order id for the first time verify that it doesn't exist with a quick API call. This will let us increment it if the id exists. Sometimes the id can exist in situations where a normal cancellation didn't occur. For example if user reaches quickpay then uses browser back or just exits the page then goes back to the site and views their basket again. Treat those as cancellation increments.
