Re-ran all nine on containers removed beforehand, one suite at a time.
All nine pass. mysql_replica_position_tests failed the first time on test
18's lag assertion, with the pair half a minute old and still catching up,
and passed on a second run against the same containers; it fails before
the point where it changes the replica's settings, so it leaves nothing to
restore. Noted both, with each suite's time.
The table's STORE column said "default" for five suites, which reads as
"leave it unset". The harness has no default: it panics with "Missing or
invalid store type" before the suite starts. They run on RocksDb, as the
regression does, so the column now names it.
