Subject: [PATCH] MT#61052 NGCP::Template::Plugin::Utils: Do not generate bogus
 YAML on empty string

When we pass an empty string the current to_yaml() function generates
broken YAML such as "--- ''", which then breaks code parsing that
expecting valid YAML. If we pass an empty string, return an empty string
as well.
