Fix Mailing Reports
The Mailing Reports are not looking at the stats table for archived mailing.
We need to override the Mailing Summary report in the archivemailing extension so it gets data from the civicrm_mailing_archive_stat by default, and if the mailing is not there then use the regular report queries. If the information is found in the civicrm_mailing_archive_stat, then there should be no link to the detailed report for any column.
