Description
Bumped an existing 0.56.1 project to 0.57 and encountered an error on simulator start: _this._registerEvents is not a function on a clean project. Tried a new project from scratch and got the same error. Running Xcode 10 Beta.
Same error was mentioned in the following ticket: #20712
_this._registerEvents is not a function. (In '_this._registerEvents()', '_this._registerEvents' is undefined)

Reproducible Demo
xcode-select -s /Applications/Xcode-beta.app/Contents/Developer
react-native init AwesomeProject
cd AwesomeProject
node_modules/.bin/react-native run-iosEDIT: Tried another new project and it worked this time. I guess it must be related to caching issues.
Will reopen if I can reliably reproduce.
