The template module ensures idempotence. So, if there is no diff between the files and the templates, the task should not return "changed", thus not invoking the handler. However, sometimes things may change on the server (i.e. permissions, ownership) because of various reasons. For that, you can use *changed_when* to rule out "false positives".
You could also simply remove the "Start Splunk" task and only rely on config files changes to trigger the restart of the service. This could make sense if you don't install the service through a package manager.
