Small provision fixes

I encountered some issues upon booting the vagrant setup. Issues like:
```
TASK: [Apache | Changing lock file owner/group] *******************************
failed: [default] => {"failed": true, "gid": 0, "group": "root", "item": "", "mode": "0755", "owner": "www-data", "path": "/var/lock/apache2", "size": 40, "state": "directory", "uid": 33}
msg: refusing to convert between directory and file for None
```
