[Split PE] Saving an ideal, bancontact or SEPA card doesn't save the card when purchasing a regular product on the checkout.

[mattallan]

Describe the bug

On the latest add/deferred-intent development branch, purchasing a regular WC product with any APM that is reusable (iDeal, Bancontact, SEPA) and selecting the "save card" checkbox on the checkout, doesn't save the card for future payments:

If you add a subscription product to your cart and purchase with any APM, the token is saved.

To Reproduce Steps to reproduce the behavior:

1. Checkout add/deferred-intent branch and make sure you have UPE enabled along with Bancontact (set your store currency to EUR if not already)
2. Add a regular WC product to your cart and on checkout, select bancontact
3. Check the "save information for future purchases" checkbox and complete the checkout
4. Add a subscription product to your cart this and go to the checkout
5. Notice how the card previously used hasn't been saved :x:
6. Complete purchasing the subscription with bancontact.
7. Once on the order thank-you page, go back and add a product to your cart and once on the checkout, confirm the bancontact payment token was saved when purchasing a subscription only.

Expected behavior Selecting "Save payment information to my account for future purchases." with any product in the cart should save the payment token. Not just subscription products.
