queue is ignoring priority if job has delay option too.

Description

Priority queues are working great. But if I add delay option to job, priority value seems to get ignored.

Test code to reproduce

const Queue = require('bull');
var priorityQueue = new Queue('priorityQueue', 'redis://127.0.0.1:6379');

priorityQueue.process(function(job){
    console.log(`processing job ${job.id} priority: ${job.data.p}`);
    return Promise.resolve();
});

priorityQueue.add({p: 2}, {priority:2 ,delay:10});
priorityQueue.add({p: 1}, {priority:1 ,delay:10});

Bull version

3.3.9
