fix runIOS: appPath is hardcoded, read from log 

Summary:
The runIOS command currently assumes the path to the `xcodebuild` product - it's hardcoded

```
  const appPath = `build/Build/Products/Debug-iphonesimulator/${inferredSchemeName}.app`;
```
https://github.com/facebook/react-native/blob/master/local-cli/runIOS/runIOS.js#L87

This can be a problem, when you e.g. install a release version of the app to the simulator using the cli. We use a separate schema for that, which can be selected with `--scheme`.

This fix reads the output of the `xcodebuild` call and searches for the path and the name of the *.app file. If it's found, then it will be used to spawn in the simulator. If not, the default (as before) is used.
Closes https://github.com/facebook/react-native/pull/8250
