Michał Pierzchała 27d4924a58 feat: refactor install to use link directly instead of spawning it (#180 )

Summary:
---------

Attempt No. 2 after https://github.com/react-native-community/react-native-cli/pull/178. Turned out I passed empty array as `platforms` argument to link, while I should pass `undefined`. We could actually add `--platforms` support to `install`/`uninstall` now, what do you think?

Test Plan:
----------

Uninstalling:

React Native CLI

Command Line Interface for React Native.

Note: CLI has been extracted from core react-native as a part of "Lean Core" effort. Please read this blog post for more details.

About

This repository contains tools and helpers for React Native projects in form of a CLI. We want to make a couple of things clear for you first:

this is a monorepo;
there are currently two CLIs: the actual one called @react-native-community/cli that does all the job and global react-native-cli which is used as its proxy;

We know it's confusing, but we're actively working to make this indirection gone.

Creating a new React Native project

To start a new React Native project, you'll need to install a global module react-native-cli and follow instructions there.

We strongly encourage you to only use global react-native-cli for bootstrapping new projects. Use local version for everything else.

Usage in existing React Native project

Once you're inside an existing project, a local react-native binary will be available for you to use. Feel free to use Yarn to call it directly.

Example running start command in terminal:

yarn react-native start
# or if you don't use Yarn:
node ./node_modules/.bin/react-native start

You can also add npm scripts to call it with whichever package manager you use:

{
  "scripts": {
    "start": "react-native start"
  }
}
