fix(workouts): refresh the Insights Workouts pill after a workout write

The tab strip shows the Workouts pill from the presence read, which
stays fresh for five minutes and was not part of the workout write's
invalidation. After the first manual workout, or after deleting the
last one, the pill stayed missing or stayed on for up to five minutes.
