Online recurring contribution via Authorize.net does not create contribution_recur record

I tested this in test-drive mode (action=preview) using the test credentials in CiviSeleniumTestCase.php webtestAddPaymentProcessor().

1. Change processor for sample contribution page 1 to Auth.net
2. Test-drive this page ( I did it as anonymous ). I selected $10 each 1 month for 12 months.

• Recurring contribution appears to work. Thank-you page shows recurring contribution schedule.
• However, if you view the test contribution (via Find Contributions -> Test Contributions) it does not show as "recurring" AND there is no record created in civicrm_contribution_recur

NOTE: If you do the same test using the back-office "Submit Credit Card Contribution" with mode=test, things work properly. You get a test contribution and a record in contribution_recur. The contribution status in Pending - Incomplete Transaction as expected since we don't get the ping-back from the Auth.net server.
