Bad matching on card create success, stripe_map_to_struct

[begedin]

Triggered by creating a card in the following process:

Client creates token using test publishable key, and the following information:

card_number: 4242 4242 4242 4242
card_cvc: 123
exp_year: 2016
exp_month: 11

The stripe request passes and the card is returned, but the mapper fails.
