Fixed crash if no-ansi option is selected

Not sure if it is the best way to fix that, but it works.

Detail on the issue : 

```
php vendor/bin/sami.php --no-ansi  update _sami/sami.php --force
 Updating project

 Version    Updated C    Removed C



  [ErrorException]
  Warning: Invalid argument supplied for foreach() in /home/lyrixx/dev/lifestream-doc/vendor/sami/sami/Sami/Console/Command/Command.php line 208



update [--force] config
```

BTW, the bug exists also with `--no-ansi --quiet`
