title: Can't set color of statusbar with cordova-plugin-statusbar
body: <p>I'm trying to change the color of the native status bar in an ionic app, but I can't get it to work. I've installed cordova-plugin-statusbar, and it installs fine. The following code works perfectly:</p>
  
  <pre><code>if (StatusBar) {
      StatusBar.hide();
  }
  </code></pre>
  
  <p>But trying to use any other of the available functions, for example:</p>
  
  <pre><code>if (StatusBar) {
      StatusBar.backgroundColorByHex('#RRGGBB');
  }
  </code></pre>
  
  <p>doesn't work, the just app uses the standard statusbar.</p>
  
  <p>I've also added <code>&lt;preference name="StatusBarOverlaysWebView" value="true" /&gt;</code> to config.xml, as well as setting it programmatically at runtime.</p>
  
  <p>Cordova is version 5.1.1, Ionic is version 1.5.5 and I'm using Android 21 for testing. Has anyone experienced the same problem or know how to fix it?</p>
