Don't retry RDE upload tasks that have failed dependencies

New upload tasks are created every 4 hours, so if we're waiting on a 2 hour SFTP cooldown or some other long-running dependency like generating the RDE report, just delete this task and let it re-run at the next 4 hour period.  No need to let these tasks continue gumming up the queue.

Note that this method of throwing NoContentException to abort the task without enqueuing it for retry is already being used by RdeReportAction for the same purpose.
