title: Alerts in elastalert are silenced when shouldn't
body: <p>I want to receive alert for each hit of query. I use rule with "any" type. Documentation says set realert to 0 so I added next lines to config.yaml:</p>
  
  <pre><code>realert:
    minutes: 0
  </code></pre>
  
  <p>but I still see in logs</p>
  
  <pre><code>INFO:elastalert:Queried rule Client errors from 2016-07-28 21:23 UTC to 2016-07-28 21:38 UTC: 16 / 16 hits
  INFO:elastalert:Alert sent to Telegram
  INFO:elastalert:Ignoring match for silenced rule Client errors
  INFO:elastalert:Ignoring match for silenced rule Client errors
  INFO:elastalert:Ignoring match for silenced rule Client errors
  ....
  </code></pre>
  
  <p>and I receive only first alert. What else could be wrong?</p>
