title: Stripe presentWithSetupIntent does not show the PaymentSheet for SetupIntents
body: <p>I've tested the Stripe's PaymentSheet for PaymentIntents, passing the payment intent client secret, the customer id and the ephemeral key.
  I succeeded on closing a payment, both with and without the bank verification step.</p>
  <p>I'm trying to use the <code>SetupIntent</code> because I need to authorize now a payment but to bill users in the future. So I've generated a scheduled subscription for a customer and obtained a setup intent client secret.</p>
  <p>My problem is, when I call</p>
  <pre><code>paymentSheet.presentWithSetupIntent(
      setupIntentClientSecret,
      PaymentSheet.Configuration(
          merchantDisplayName = Constants.MERCHANT,
          customer = PaymentSheet.CustomerConfiguration(
              customerId,
              ephemeralKeySecret
          )
      )
  )
  </code></pre>
  <p>I see the payment sheet coming out from the bottom with only an infinite progress bar, as if the setup intent was invalid.</p>
