Delete defunct spec

From a comment on Github:

> In this particular case, the spec is broken, actually. I just looked into it and you are right that StripeSCA supports payment profiles but the spec finds that the profile is not stored. And that is because `source.try(:save_requested_by_customer?)` returns false. We only store the profile when the customer is storing their credit card info.
