Restored quick database reset method via table truncation

refs a3cc66be50

- in the referenced commit, I made a util to speed up resetting the DB
  for SQLite by copying the database file
- I inadvertently removed an optimization we had before - where we
  truncate the tables and insert the fixtures instead of dropping the
  entire database
- this would be missing on MySQL tests
- this seems to have a big difference so this commit re-adds the
  optimization in
