Should exit with non-zero status if not configured

[salomvary]

When surge is executed in non-interactive mode (eg. from a CI) and is not properly configured, it exits with zero status suggesting everything went well.

Expected: it should exit with non-zero status signalling a failure.

Version: 0.19.0

Steps to reproduce:

 $ echo "" | surge --project .

    Welcome to Surge! (surge.sh)

              email: 
$ echo $?
0
