Removing items in queue using queue.clear function yield strange behaviors

[TomShen1234]

Describe the bug

See below.

To Reproduce

If a job is dispatched to the queue with a delay:

func dispatchJob(on req: Request) -> EventLoopFuture<Void> {
    let newDate = Date().addingTimeInterval(30)
    req.logger.info("Dispatching job at: \(newDate)")
    return req.queue.dispatch(TestJob.self, .init(id: UUID()), delayUntil: newDate, id: JobIdentifier(string: "test-queue-item"))
}

...and you want to cancel it, the only method that appears to do the action is:

req.queue.clear(JobIdentifier(string: "test-queue-item"))

By doing this, what it appears to do is that it removed the actual job information from the Redis database. However, the job is now in the vapor_queues[default]-processing list, but since the actual job information is removed, the console now logs: [ ERROR ] Job run failed: missingJob. From this I assume that this method is only used internally for dequeueing jobs? Especially if I want to reschedule the job with the same JobItentifier, strange behaviors like duplicate dequeues will happen.

If this is the case, can we get a function to remove a dispatched job from the queue? Otherwise, this will be a bug report.

Expected behavior

The item should be removed from the queue properly.
