Broke composer commands when used with phpcodesniffer-composer-installer

[mickaelperrin]

Hi,

I am not sure which one is causing the issue, but I just noticed that using at the same time this package with dealerdirect/phpcodesniffer-composer-installer broke composer post install commands.

Steps to reproduce

1. Create a minimal composer.json file:

{
  "require": {
    "php": ">=7.0.0"
  },
	"require-dev": {
		"wp-cli/package-command": "*@stable",
		"dealerdirect/phpcodesniffer-composer-installer": "*"
	},
  "scripts": {
    "post-install-message": [
      "echo 'Oooops'"
    ],
    "post-install-cmd": [
      "composer run post-install-message"
    ],
    "post-update-cmd": [
      "composer run post-install-message"
    ]
  }
}

2. Run composer install

Result

> post-update-cmd: composer run post-install-message
Executing command (CWD): composer run post-install-message

Fatal error: Uncaught Error: Class 'Symfony\Component\Process\ProcessBuilder' not found in /src/test/vendor/dealerdirect/phpcodesniffer-composer-installer/src/Plugin.php:118

It has been crossposted to PHPCSStandards/composer-installer#59
