In order to fix gitlab-ce#29626, we added support for detecting unhandled promise rejections in ESLint with gitlab-ce!9969. We also added catch (for unhandled Promises) and fail (for jQuery Deferreds) with gitlab-ce!9991. But there are several callbacks present which are still empty, those callbacks need to have proper handling of Promise rejections as well as failed jQuery Ajax calls.
