Update Element Template Feature broken

Describe the Bug

Update Element Template Feature broken

Steps to Reproduce

1. Have multiple templates from Cawemo synced
2. Apply one template
3. => note that even though the template does not have a newer version, one can apply a new version. => the actual template is changed

(It seems the update logic does not filter on template id?)

Expected Behavior

Update element template logic only available for template with the same ID (and multiple versions)

Environment

#161

It seems that we'd need to re-render the templates group whenever templates are changed.

Indeed we don't check the template ID o.O
