fix display of not found hints

originally this identifier had to be added to the main template
but since we added the additional overview_list.tmpl for providing a clear context
the identifier "no_result_info" was not replaced anymore. Now I added it to this "new" template

I could have added it to a local overwrite in my project, but I think this is a good default feature of the plugin that existed before
