Missing lock for job failed when closing queue and job takes more than 30 seconds to complete [BUG]

Created by: misos1

Description

Seems job which takes more than 30 seconds to complete is not properly finished when is queue closing and in next runs is announces as stalled. Additionally it takes another 5 seconds to gracefully exit after is queue closed which does not happen when job takes less than 30 seconds to complete.

Minimal, Working Test code to reproduce the issue.

let Promise = require("bluebird");
let Queue = require("bull");
let queue = new Queue("queue");
queue.process(10, _job => Promise.delay(40000));
queue.on("error", (...errs) => console.log(new Date(), "queue error:", ...errs.reverse()));
queue.on("stalled", job => console.log(new Date(), "stalled", job.id));
(async function()
{
	let job = await queue.add({});
	console.log(new Date(), "added", job.id);
	await Promise.delay(1000);
	await queue.close();
	console.log(new Date(), "closed");
})();
process.on("exit", () => console.log(new Date(), "exiting"));

Possible output after few runs:

Additional information

Nothing which I described happens if I change it to 20 seconds:

queue.process(10, _job => Promise.delay(20000));
