Only use the GITHUB_API_TOKEN if it's not empty

Unfortunately the Ruby ENV['foo'] returns true regardless or not if the value is empty or not.

I was having some issues with a terminal session where I purposefully set all env variables to blank for when I'm screen sharing and then puppet-librarian kept failing with a 401. Looking it up it was because it was calling https://api.github.com/foo?page=1&per_page=100?access_token=

I put in a Puts to alert the user, but can remove if needed

Thanks, could you use debug { "..." } instead of the puts ?
also, it'd be nice to avoid the code duplication and create a new method to append the api token to any url
