Ensure all create events have a snapshot NID of 0 (#1961)
Fixes #1924 for postgres users, though the underlying cause of why
they aren't 0 in the first place is unresolved.

* db migration: fix #1844 and add additional assertions

- Migration scripts will now check to see if there are any unconverted
  snapshot IDs and fail the migration if there are any. This should
  prevent people from getting a corrupt database in the event the root
  cause is still unknown.
- Add an ORDER BY clause when doing batch queries in the postgres
  migration. LIMIT and OFFSET without ORDER BY are undefined and must
  not be relied upon to produce a deterministic ordering (e.g row order).
  See https://www.postgresql.org/docs/current/queries-limit.html
