'phantomjs-prebuilt/node_modules' folder is removed after a second 'npm install'

Hi,

We've found a very weird bug with phantomjs-prebuilt@2.1.9. These are the steps for reproduce the problem:

• First 'npm install' -> all dependencies installed correctly.
• Second 'npm install' -> /my_app/node_modules/phantomjs-prebuilt/node_modules/ folder is removed (around 100 packages)
• Third 'npm install' -> npm ERR! enoent ENOENT: no such file or directory, chmod '/my_app/node_modules/phantomjs-prebuilt/node_modules/extract-zip/node_modules/mkdirp/bin/cmd.js'

OS: Linux Ubuntu 16.04/14.0, Centos 7.2 Node: 5.2.0 NPM: 3.3.12
