Retry will not fire success callbacks

Callbacks defined with `.success` will not be fired. See http://stackoverflow.com/questions/11793430/retry-a-jquery-ajax-request-which-has-callbacks-attached-to-its-deferred

Start by reproducing the retry behavior described in the issue and compare it with the linked Stack Overflow example. Trace the jQuery AJAX wrapper's retry path and verify that callbacks attached with `.success` still run after a retry; done means the reported callback behavior is corrected.
