ref(backup): More auto-deduced options datetime comparators

Previously, we only auto-deduced (from model field types) datetime
equality comparators for fields that were already in the comparator map.
This caused us to miss a lot of datetimes! Now we're more careful about
this, with many more such comparators caught.

I've also removed the snapshot test, and tested the exports directly
instead, ensuring that they always include milliseconds in datetimes.
