A booting HA must not split the cleanup run

At startup the vacuum entity reads unavailable; the recorder took that
for 'stopped' and ended the open run, so every HA restart mid-cleanup
rotated the trail into previous and began a fresh one (observed live:
a 21-point run became previous and restarted at 5). Unavailable and
unknown now mean 'no verdict'.
