failedReason and stacktrace not in Queue.on('failed') and on('error') not triggering

Created by: alecl

Seems like these should be there given there's interested in the failures if you're handling the failed event, no? If I call Queue.getJob these two fields are there.

Also, I was surprised that Queue.on('error') doesn't get triggered whether I throw an error inside process or pass an error object to the callback. Looking at the code seems this even is mainly for Redis connection errors and not job errors?
