speed up transaction storage a bit

by updating existing records in-place. sqlite's insert or replace
statement tries insert, and when that fails because of unique/primary
key violation *removes* the existing record together with any child
records and then retries the insert. it is almost like deleting all the
transactions and inserting them again, but with a failed insert before
that
