title: Resque scheduler recurring job update issue
body: <p>I have a recurring job in my application that runs every 2 hours that got updated recently, and it seems the scheduler somehow has cached or ignored the changes made to this job.</p>
  
  <p>If I connect to the server via SSH and open the file I can see the changes, and if I run the the job through the rails console everything works fine. But when the scheduler runs the job after 2 hours, it omits a counter that was added on the changes.</p>
  
  <p>Any ideas of what could be going on here?</p>
  
  <p><code>resque (1.23.0)</code>
  <code>resque-scheduler (2.2.0)</code></p>
