epriestley a30a9a8353 Give users meaningful error messages for missing 'arc' credentials
Summary:
We give you a worthless message that doesn't point at "arc install-certificate"
if you don't have an .arcrc right now. Instead, tell the user to run "arc
install-certificate".

Test Plan:
Nuked my ~/.arcrc and tried to run "arc list".
