Fixe SEGV when use one delegated job and one or more failled jobs.

[Franck Lombardi]

In this sample : 
a2ps foo.deleg bar.none
foo.deleg is a delegated job and bar.none don't exist

This sample SEGV, because a2ps has only been used to delegate a single job. 
And in this case we work with "CURRENT_FILE (job)". If a failed job is after 
the delegated job, CURRENT_FILE (job) == the failed job.

My solution is find the last job who don't a failed job.

A other solution is to del the failed job when it is detected as a failed job 
but it is a more big patch.
