Summary: Fixes T9369.

Test Plan:
  - Sent a mail with Mail.app to `bugs@local.phacility.com`.
  - Used "View Raw Mail", copy-pasted it into `mail.txt` on disk.
  - Ran `cat mail.txt | ./scripts/mail/manage_mail.php --process-duplicates`.
  - Saw task get created and me get added as CC.
  - Changed "To" to include another user, ran command again, saw task get created and other user get added as CC.
