Always return Stripe\Card when calling Stripe\Token->card

[ruudk]

Currently, it returns an AttachedObject, while I think it should return a Card

I now have to do this:

public function getCard(string $token) : Card {
    $token = Token::retrieve($token);
    return Util::convertToStripeObject($token->card->__toArray(), null);
}

and that looks very ugly :D

Hi @ruudk. This is a known issue described here. We have a fix pending in #396 but it's turning out to be slightly more complex than anticipated.

We're still going to fix this, but OOC, why do you need the card property to be a card object?
