Prevent restart with no server credentials which causes exit code 1

This is a solution for someone who wants to install blackfire without setting the server credentials right away, such as in public vagrant boxes. Prior to this, on server restart, chef-solo would exit due to exit code 1 from the service restart operation, and the provisioning would fail.
