Previously, using the bulk delete tool in the Django admin for `CertificateDateOverride`s would not trigger the post to the credentials service to delete the corresponding date override stored there. This was because we were sending the COURSE_CERT_CHANGED signal from an overridden version of the delete() method. But the Django docs warn: "Note that the delete() method for an object is not necessarily called when deleting objects in bulk using a QuerySet or as a result of a cascading delete. To ensure customized delete logic gets executed, you can use pre_delete and/or post_delete signals." Now we use the post_delete signal instead of overriding the delete() method to make sure the COURSE_CERT_CHANGED signal is sent for both individual and bulk deletes. MICROBA-1487
