Fix usage of react-native cli inside package.json scripts 

Summary:
IIRC we made `wrong-react-native` to warn people in case they installed `react-native` globally (instead of `react-native-cli` what the guide suggests). To do that we added `bin` entry to React Native's `package.json` that points to `local-cli/wrong-react-native.js`

However, this means that if we have a project that uses `react-native` package and has call to `react-native` CLI inside its package.json, npm will execute *local* override (which just prints a confusing in this context error message).

In fact, the template we generate with `react-native init` has `react-native start` as `start` script, which makes it useless. Let's fix it by making `wrong-react-native` script smarter – it can detect that it has been executed from local `node_modules` and run the actual CLI.
