Merge the accepted-routine fix and drop reminder_id from accept

Two merge fixes on top of the branch:

- migrations: keep both new steps, snooze stays #8, the routine columns
  become #9. Both agents had numbered theirs #8.
- accepting no longer takes a reminder id, on the web surface too. The
  web accept path had the same one-shot-reminder bug the voice path did,
  so both now just flip the status and let the tick loop schedule.

The test that asserted "accept creates a reminder and links it" asserted
the bug. It now asserts that accepting creates no reminder.
