title: console.error in react-native throws red screen even when __DEV__ is false
body: <p>I'm building react-native app with Exponent and do some logging with <code>console.error</code> e.g. when network request fails etc. While it's helpful in development to see this red screen with error on simulator or real device, I'm getting this too when <code>__DEV__</code> is set to <code>false</code> (seeing it is set so in logs) while the web says it shouldn't work like this.</p>
  
  <p>How can I disable that for non-dev builds? Is there any other way than monkey-patching <code>console.error</code>?</p>
