CRON SendAlerts : can't use `parseArticles` hook

[ChipsVII]

The parseArticles hooks expects an instance of \Contao\Module as its 3rd parameter, but we cannot provide any at this moment. So the hook usage is disabled until a solution is found.

[LupusVII]

It was a "dumb" copy and paste from Contao code, you can trash it when you have the opportunity.
