Update all content fails to update template adjustment

A secondary problem is that there's no way to delete the template, hence all update all content actions in the future will fail. Only editing through the console or restarting with a clean repository can resolve this issue.

Reproduction with quickstart:

• create new namespace
• create new template
• add string field
• click done
• update all content
• edit the new template again
• add compound field "Extended Rich Editor"
• click done
• update all content
  -> Failure
