Fails to compile: RCTFabricUIManagerWrapper.h is included when using Cocoapods [0.55.x regression]

[almostintuitive]

• I have reviewed the documentation
• I have searched existing issues
• I am using the latest React Native version

The file RCTFabricUIManagerWrapper.h is included included when using Cocoapods (the local "React" pod). RCTFabricUIManagerWrapper.h does not compile: it throws an error that folly-config.h is not found.

The app builds fine with react-native 0.54.x.

The root cause of the problem is that this specific file is unintentionally included among the compiled files. According to @fkgozali 's comment on #17764

Environment

Environment:
OS: macOS High Sierra 10.13.3
Node: 9.10.1
Yarn: 1.5.1
npm: 5.6.0
Watchman: 4.9.0
Xcode: Xcode 9.3 Build version 9E145
Android Studio: 3.0 AI-171.4443003

Packages: (wanted => installed)
react: 16.3.1 => 16.3.1
react-native: 0.55.1 => 0.55.1

Steps to Reproduce

1. Create a new Xcode project
2. Follow the guide how to integrate react-native into an existing project
3. Run the app

Expected Behavior

The app builds without an error.

Actual Behavior

The app does not compile

@fkgozali originally CCd @shergin & @hramos, so I'll do that here as well.

Thanks for the report. I think this was addressed with #18688 (now in master).

@hramos: may want to get that fix picked to 0.55 or whatever the latest release is?

[hramos]

@fkgozali for sure. @ptomasroos requested this be cherry-picked into 0.55 here: react-native-community/releases#11 (comment)
