Ensure we don't get silent errors if the Lua code is longer than the
database column, don't leave out the first report from testing, test
fetching multiple reports.
This is done by requiring 'parseTime=true' in the MySQL DSN's (required
by github.com/go-sql-driver/mysql when Scan()ing to time.Time's), and
not forcing update counts to match if rows were updated to what they
already were.
