Update laravel_app/manifests/init.pp

Added requirement for apache2 to be installed before Exec['clean www directory'] is ran.

When the apache2 package is installed, it places an 'index.html' file in the "/var/www/" folder, which causes the Exec['create laravel project'] to later fail (since the directory is no longer empty).

Hopefully, this will help prevent the issue from happening to others.
