ERROR [2022-10-24 02:05:15] 2060 Scheduler: Error User 'MyUsername' doesn't exist. for task 'Piwik\Plugins\CoreAdminHome\Tasks.checkSiteHasTrackedVisits_3'

Expected:

Error is caught in https://github.com/matomo-org/matomo/blob/4.12.2/plugins/CoreAdminHome/Tasks.php#L164-L169 as we would otherwise just return anyway if email not found

Thanks @tsteur, so just to clarify - the checkSiteHasTrackedVisits scheduled task is trying to find the user who created the site, but if that user no longer exists, instead of throwing an exception, we should simply abort the task and return 👍

I've scheduled this for prioritization.
