Bug 36127: Adjust default HOLDPLACED and HOLD_CHANGED notices to use TT

To test:
1. Apply patch
2. reset_all (or start your testing environment in the first place)
3. Edit system preferences:
     emailLibrarianWhenHoldIsPlaced - Enable
     ReplyToDefault - enter a fake/test email address
     ExpireReservesMaxPickupDelay - Allow
     ExpireReservesAutoFill - Do
     ExpireReservesAutoFillEmail - same email address as ReplyToDefault
4. Place two holds on the same bib for two different patrons, Patron A
   and Patron B
5. Edit an item on that bib to set a call number (if it doesn't have one
   already)
6. Check in that item to set Patron A's hold to waiting
7. Edit the expiration date on Patron A's hold to yesterday's date
   To do this in KTD:
     ktd --shell
     koha-mysql kohadev
     UPDATE reserves SET expirationdate = <yesterday's date>
     WHERE borrowernumber = <Patron A's borrowernumber>;
8. Run misc/cronjobs/holds/cancel_expired_holds.pl to automatically
   cancel the expired hold and fill the next one
9. Open koha-mysql again and run the following query to view the
   generated notices:
   SELECT subject, content FROM message_queue
   WHERE to_address = '<the email address you set in step 3>';
--> Confirm that HOLDPLACED and HOLD_CHANGED notices were both generated
--> Confirm that all information has been filled in correctly for those
    notices
