Check for 'Generated' in SSH key comment

This test fails for https://review.openstack.org/76904 (replace spaces with
dashes in Nova generated SSH key comments) and thus prevents 76904 from
merging. This change simply checks for 'Generated' in the SSH key comment
instead of 'Generated by' which contains a problematic space.
