XavierDo 62591c58f8 [FIX] mail: add ability to mark failure notification as read ...

The mark as read button was not working for mail failure. More than that,
we wanted a functionnality to be able to massively mark mail failure as canceled,
especially to be able to clean databases from failure after migration.
