StatusStorage::SQLite: bug fix: always use array-refs records instead of hash-refs for SQL::Maker's update() and insert() method.
Order of hash keys is indeterminate, even in the same process.
So if we use hash-refs for records that are inserted/updated in bulk operation,
SQL::Maker's $sql result is different for every record.
In that case, we cannot re-use the $sth obtained by $dbh->prepare().
Now we sort keys in hash-ref records and convert them into array-refs,
so that $sql is always stable.
xt/StatusStorage_Memory: use =~ instead of ~~ because ~~ is experimental.
