Bug 28221: Script process_message_queue.pl uses Try::Tiny but doesn't 'use' it

Bug 28221: Script process_message_queue.pl uses Try::Tiny but doesn't 'use' it

The message queue processor has a try/catch block, but does not have a 'use Try::Tiny' line. Because of this the following error ocurrs if an instance has any plugins installed that use the before_send_messages hook:

Can't locate object method "catch" via package "1" (perhaps you forgot to load "1"?) at /usr/share/koha/bin/cronjobs/process_message_queue.pl line 86.

Test Plan:
1) Install a plugin that uses the before_send_messages hook
2) Run the message queue processor
3) Note the error message
4) Apply this patch
5) Run the message queue processor again
6) No error!
