minor fixes to template function

- make sure it calls itself correctly, now passes same params as it recieves
- vars is reserved, changed for templatevars to avoid confustion
- forcing mustaches again since the removal broke 'listification' as per #9622
- fixes incorrectly successful tests using undefined var, now it is defined
- now returns empty list if items is None to avoid errors
