Instead of granting a coupon when purchasing a package, grant credit. This changes paymentsconfig.PackagePlan to use credit amount rather than coupon ID. Add additional check to see if a paid invoice with the description exists. If so, don't create and pay another invoice. Change-Id: I81df24984c519c773db5fc8e9070bd7797070ec2
