title: Cordova - white screen after splash, no exceptions in console
body: <p>I've been away from my Cordova app for a bit, but just did a fresh clone yesterday and noticed that it's got the "white screen of death" symptoms -- the splash screen displays, the program loads... and then I just get a blank screen. Some more details:</p>
  
  <ul>
  <li>CLI: Cordova 6.1.1, android 5.1.1, ios 4.1.1</li>
  <li>I'm not using any special plugins to display a splash screen -- just <code>&lt;splash&gt;</code> elements in <a href="https://github.com/adapt-it/adapt-it-mobile/blob/master/www/config.xml">my config.xml file</a>.</li>
  <li>This is happening in both iOS and Android, both on local builds and using PhoneGap Build (i.e., debug and release).</li>
  <li>There are no exceptions of missing resources in the console, either in iOS (using Safari's dev tools) or Android (using Chrome's dev tools).</li>
  <li>I've done a <a href="https://github.com/adapt-it/adapt-it-mobile/compare/65b70a3e782f82c6e05c21e687f2b7987889e320...master">diff with my last known working build</a>, and there's really nothing that pops out. I saw an undefined Underscore reference, but I backed that change out and it didn't resolve anything -- I think I'd see the exception in the console, anyway.</li>
  </ul>
  
  <p>Has Cordova / PhoneGap done something recently that might be causing this? Any ideas on how to isolate this one? I'm really stumped.</p>
