fix(test): MariaDB 11 upgrade, query result order
Fix order of recipients for "FlagNotification" test.
Apply sorting to the recipients query. -> Only relevant for tests, but who knows when they change things again
(there is no impact on performance)
MariaDB 11 includes some changes related to the query optimizer.
Turns out that this might have effects on how records are ordered for certain queries.
(in case no ORDER BY clause was specified)
