admin/origin_save: Do not modify unauthorized URLs list when rejecting
When rejecting a Save Code Now request, the submitted origin URL was automatically added to the unauthorized URLs list. But this was prolematic as a valid URL prefix could be added in that list and thus a valid request whose origin URL has that prefix would be automatically rejected.
So remove the automatic adding of origin URL in unauthorized list when rejecting a request.
