title: Laravel Queue Jobs are automatically processing without any queue:work or listen command
body: <p>I am queuing jobs to run after 1 minute from my controller and jobs appear in "jobs" table correctly, but as per doc I have to run php artisan queue:work to get jobs executed but in my case they are being executed without any command on Ubuntu server (AWS ec2). Also such jobs go to failed jobs table as they are reading some old code of controller which I changed earlier.
  Note: If I run php artisan queue:work, then some of the jobs are processed by this and get executed with new code without generating any error while some of the jobs are executed by that unknown background process and generates old code error</p>
