Stripe Gateway: "Must provide source or customer." about gringotts HOT 2 OPEN

I've gotten a bit further with this issue. Apparently Gringotts.store returns a map containing an id for a customer, but it doesn't save the card it was called with (the cards entry in the returned map has %{"count" => 0}.

The error I see now is:
Cannot charge a customer that has no active card

As far as I can tell, Gringotts.store is storing neither the credit card nor the address I'm feeding into it. Is this a bug?

Ideally, Gringotts.store would store both the credit card (as the customer's default) and the address in a new customer, and Gringotts.unstore would fetch the customer_id, the credit card, and the address (perhaps in a map?), and then subsequently delete the customer via Stripe's API.

Then Gringotts.authorize and Gringotts.capture would just take an additional [customer: customer_id] in the opts list.
