Config for wordpress-trunk.dev not available after initial `vagrant up`

I did a `vagrant up` from scratch with Salty WordPress tonight and it seems that the [wp-cli commands] (https://github.com/humanmade/Salty-WordPress/blob/master/config/salt/vagrant.sls#L17) didn't run properly during provisioning. No `wp-config.php` file was created.

A subsequent `vagrant provision` caused the commands to run fine, `wp-config.php` was created successfully, and `http://wordpress-trunk.dev` worked as expected.
