[Membership 2 Pro] Stripe Coupon Name Fix

Currently when using Stripe Subscription Plan payment gateway and Coupons, the coupons generated on the Stripe account use:
'id' => self::get_the_id( $coupon->id, 'coupon' ),
Unfortunately this means that the coupon name ends up being something like: ms-coupon-8252-6qFQjkSSg4xNr4svs1p6X6
Unfortunately this also means that this crazy ID is what's shown to users when sending invoices and confirmation receipts using Stripe. It would be much nicer to see the name of the coupon (for example BACKTOSCHOOL30) as the ID. That would make things much cleaner not only in the Dashboard, but also in the Stripe invoices/receipts.

Can this be updated please?
