Bug 11561: restore previous behavior of generation of hold print notices

Bug 11561: restore previous behavior of generation of hold print notices

This patch prevents duplicate hold available print notices from being
sent and enforces making a print notice if no other transports can be
used.

-------------------------
- REPLICATING THE ISSUE -
-------------------------

1. Set a Patrons "Hold filled"-messaging preference to SMS + Email
2. Remove the SMS number (sms notification number) and all email
   addresses.
3. Make a reservation for this Patron.
4. Check-in the reserved Item.
5. message_queue-table has two generated print notices for the
   Hold_filled event.
   One for both failed message transport types, email and sms.

1. Set a Patrons "Hold filled"-messaging preference to empty, remove all
   checks from boxes.
2. Make a reservation for this Patron
3. Check-in the reserved Item.
4. message_queue-table has no message for the Hold-filled event. This is
   problematic because a Patron should get some kind of a notification
   for a filled Hold.

-----------------------------
- AFTER APPLYING THIS PATCH -
-----------------------------

If all message transport types for "Hold filled" fail, a print notice is
queued in the message_queue table. Only one print message is queued even
if many transports attempts fail.
