Throws fatal error if main config folder doesn't exist

[beloglazov91]

After installing so-sli package on Linux OS and calling so command I've got the following problem:

➜  ~ so
PHP Fatal error:  Uncaught RuntimeException: /home/beloglazov91/.config/so-cli is not a directory in /home/beloglazov91/.config/composer/vendor/systemseed/so-cli/src/Configuration.php:102

When I created ~/.config/so-cli manually that error disappeared.
