Martin Konicek ca403f0a5f Use Yarn if available
Summary:
**Motivation**

If the project is using yarn to manage its dependencies, we should be running 'yarn add' to upgrade the React Native dependency, rather than 'npm install'.

**Test plan (required)**

Running in a project that's in a bad state:

    Error: react-native version in "package.json" (0.29.2) doesn't match the installed version in "node_modules" (0.38.0).
    Try running "yarn" to fix this.

Removed yarn.lock file, ran again:

    Error: react-native version in "package.json" (0.29.2) doesn't match the installed version in "node_modules" (0.38.0).
    Try running "npm install" to fix this.

Running inside a folder that doesn't contain a `package.json` file:

    Error: Unable to find "/Users/mkonicek/Zero29App/package.json" or "/Users/mkonicek/Zero29App/node_modules/react-native/package.json". Make sure you ran "yarn" and that you are inside a React Native project.

Removed yarn.lock file, ran again:

    Error: Unable to find "/Users/mkonicek/Zero29App/package.json" or "/Users/
