No email sent when "publish" job fails

[tidoust]

Apparently, Echidna does not to send any email to the public-tr-notifications mailing-list when the publish job fails.

An example of a job that was started at about 2015-06-30T22:07:17Z:

... Here is a copy of the task status in JSON if that link disappears:

}

Note: the failure in that case was due to #201 and was easy to fix. This issue is really just about not receiving the failure notification on the mailing-list.

@deniak hopefully just fixed this in #216.
I'm keeping this open until we confirm in production.
