The default values for the $ssl_*_contents parameters is undef, so checking whether they match empty string is not sensible. Fix the conditionals to check for the case when the user has left the value unset. It is reasonable to conditionally not create these certificate files even when $site_ssl_enabled is set because the path variables may be set to a snakeoil cert.
