Fabien O'Carroll dbf564d137 Created Stripe Coupons when Offers are created
refs https://github.com/TryGhost/Team/issues/1166

We've moved the Stripe Coupon creation out of the Offers module as part
of the work for Stripe disconnect, so we have to make sure that we are
still creating coupons when an Offer is created.
