The Query "SET NAMES 'utf8'" hasd been moved to Database.class.php
and is used via parent::query because otherwise this would throw an
error and it is more logical this way.
Database::query uses Logger::debug, which uses Package::$pdb->quote.
And Package::$pdb is not available yet (because it's set afterwards
in global.php).
Unfortunately the Query won't be logged, which is (seen strictly)
bad, but the impact isn't very high. Additionally it can be seen as
a test for the Database Connection
