Switch to our own fork of the poise-javascript cookbook

Includes passing the `--no-audit` switch to `npm install` to prevent the
`npm_install` resource to consider the command resulted in changes,
causing the service to restart at every Chef run. npm returns the
expected string "up to date" when not performing the security audit

Closes #5
