[RN 0.52] RCTImageLoader requires main queue setup since it overrides init but doesn't implement requiresMainQueueSetup #17504
Description

Yes
Have you read the Contributing Guidelines?
Yes
Environment
Environment:
OS: macOS Sierra 10.12.6
Node: 9.3.0
Yarn: 1.3.2
npm: 5.6.0
Watchman: 4.9.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: Not Found
Packages: (wanted => installed)
react: 16.2.0 => 16.2.0
react-native: 0.52.0 => 0.52.0
Steps to Reproduce
$ react-native run-ios
Expected Behavior
iOS simulator run without errors.
Actual Behavior
^
Module RCTImageLoader requires main queue setup since it overrides `init` but doesn't implement `requiresMainQueueSetup`. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.
Reproducible Demo
Any app using the Image component, although in my app I wrap that in a higher level component I use: react-native-fit-image.
I've never seen RCTImageLoader complain about requiresMainQueueSetup before. Only started now after I upgraded RN from 0.51 to 0.52.
