title: React-Native: Module RCTLog is not a registered callable module
body: <p>In React-Native 0.29 and 0.30. <br/>
  When I running on iOS device using the offline bundle, always got Error information below:</p>
  
  <blockquote>
    <p>Unhandled JS Exception: Module RCTLog is not a registered callable module.<br/>RCTFatal + 124<br/>

  <pre><code>react-native bundle --entry-file ./index.ios.js --platform ios --dev false --bundle-output ./Example/index.ios.jsbundle --assets-dest ./Example/ --verbose
