Routines accepted before Vikunja #366 carry accepted_ts NULL and a live
reminder row. The tick loop reads accepted_ts to decide when a routine is
next due, so those rows have been silent since the fix landed, while the
reminder they still point at keeps firing on its own schedule.
Migration #19 cancels that reminder first, then dates the acceptance from
created_ts and lets the reminder id go. Order matters: the second update
clears the id the first one needs.
