title: whereJsonContains Laravel 5.6 not working?
body: <pre><code>$rosters = EventRosters::where('event_id', $event_id)
      -&gt;whereJsonContains('players', $user_id)
      -&gt;whereNull('deleted_at')
      -&gt;get();
  </code></pre>
  
  <p>The eloquent query above seems to only work when there is a single item in the 'players' json array.</p>
  
  <p>The data stored in the database looks as follows:
  <code>[1]</code> vs <code>["1","2"]</code></p>
  
  <p>Is there a reason the whereJsonContains is only working when it sees <code>[1]</code> in the db but not when it sees <code>["1","2"]</code> ?</p>
  
  <p>I am pretty new to Laravel and have been struggling with this one a bit.</p>
