[Evergreen-catalogers] Null values in holdings templates

[Elaine Hardy]

We don't use required stat cats, so don't have this particular issue with
holdings templates. We do set for just a couple of values and are able to
apply templates successfully.

There are a couple of bugs reported around required stat cats but I didn't
find this particular one. What happens if the template is also set to apply
those required stat cats? Does it also flip them to null?
