The problem was that we tried to upgrade the db by re-creating a LocalStore,
without closing the existing connection. The db was still upgraded on the
filesystem, but the old connection kept looking at the old table definition
for whatever reason.
Also cleaned up checkAllTablesFound(). It now shows what columns are
missing when failed.
