Hi! For various reasons I'm using a rather high lockDuration setting in my app, and I noticed that jobs that fail an attempt and have to be moved to delayed remain locked. This means that I cannot easily remove such a job from our small homegrown queue control app, as it isn't the lock-taker.
When I tried to figure out what was going on, I noticed this comment: https://github.com/OptimalBits/bull/blob/61a87a8509bfc9227775084839544c444d69994d/lib/job.js#L309
... However, it seems like the job isn't actually being unlocked by moveToDelayed-3, so I tried fixing that
