Card.io + Prefill Causing Keyboard to pop up

[corbinhudson]

Using Card.io method 'userDidProvide' I call cardTexField.prefill to populate the cardTextField with values. When I hit done on the paymentViewController, prefill is called the keyboard reappears to fill out values I've already provided. Already tried a number of resignFirstResponder fixes and nothing worked.

Thanks for filing this bug! I created #129 for this, which should resolve the issue.
