Title: Fixed PHP warning when config.yml is empty.

I created a config.yml inside the requested directory (PHPCI), and I got this warning:

`Warning: Invalid argument supplied for foreach() in /Users/tobias/Sites/PHPCI/vendor/block8/b8framework/b8/Config.php on line 141`

This pull request checks if the config is empty and if it is not it does not do anything.
