fix(tests): saves compared byte for byte don't fail when the clock crosses a second between them

The three script-refusal tests built on reset_order_session save, run a
refused edit or script, save again and compare the bytes. Each save stamps
/ModDate from the system clock, so the comparison failed whenever the two
saves fell in different seconds. The helper now pins the session clock with
Session::with_clock, as session_with and the other byte-comparing tests do.
