`solc-select versions` should indicate that there aren't any versions of solc installed instead of erroring #152

If you run solc-select versions in a fresh venv, it's expected that solc isn't installed. The error message could be more helpful instead of the current behavior:

(slither) alpharush@macbook slither % solc-select versions
