Subject: [PATCH] [REM] mail, sms, snailmail: discard notifications without
 confirmation

Skip the confirmation step when wanting to get rid of a notification
for emails, sms or letters that were not sent.

Technical:
- All 3 wizards to confirm the discarding of the notification have been removed
(the ones for mail, sms and letter) have been removed
- The method to discard notification has been centralized in MailThread
(notify_cancel_by_type in addons/mail/models/mail_thread.py)
- This centralization has been done as well on the client code as the same
server code is called whether it is a mail, a sms or a letter
(in addons/mail/static/src/models/notification_group/notification_group.js)
- Existing front and back test have been adapted
- A test of notify_cancel_by_type for mail has been added
(addons/test_mail/tests/test_mail_management.py)
- add missing author_id in mail_notification demo data

Task-2752190
