ProSites: Missing closing div tag in "gateway-stripe.php"

Just a quick fix I uncovered this evening for the Stripe payment gateway for ProSites.

Within the "#psts_existing_info" <div> of "gateway-stripe.php" file: If the "$cancel_status == 1" the "#psts_existing_info" div doesn't have a closing </div> tag.

...that's all. Loving ProSites!
