phorge-phorge/scripts/ssh/ssh-auth.php
Eric Stern 45c3a605ee Correctly handle case where no ssh keys are found
Summary: If no ssh keys are in phabricator, bin/ssh-auth errors with undefined `$lines`. This fixes that case and explicitly tells the user no rows were found.

Test Plan: Ran bin/ssh-auth before and after change with no ssh keys in the system. Error goes away after change.
