In react-native v0.52 this warning shows:
```
"RCTImageLoader requires main queue setup
since it overrides `init` but doesn't implement `requiresMainQueueSetup`".
```
This removes the warning by implementing `requiresMainQueueSetup` on RCTImageLoader
* Create new react-native project
* Enable Remote JS Debugging
* Should see no warning regarding RCTImageLoader requiring main queue setup
