Calling queue constructor w/o a name causes a background promise rejection

Created by: osher

Description

Minimal, Working Test code to reproduce the issue.

(An easy to reproduce test case will dramatically decrease the resolution time.)

code:

const Q = require('bull'); 
const r = new Q();  //<-------- not provided a name
r.add('stam', {foo: 'bar'}).then(v => console.log('added', v));

Expected

should either work with no problems, or throw an assertion early on during queue creation.

Found

There is nothing that I as a user can do to prevent this background promise rejection from happening, except for providing a name.

So what I would consider professional is that either the constructor should throw upon missing name, or there should be a baked-in default.

I'm doing it in a node shell as part of my evaluation
