Bug 21640: Enable output to STDOUT for Itiva outbound script

To test:
 1 - Enable the TalkingTechItivaPhoneNotification
 2 - Copy 'HOLD' notice 'email' transport to the phone section
 3 - Enable EnhancedMessagingPreferences
 4 - Find a patron and enable 'phone' for the 'Hold filled' notice
    Note: You might not be able to do this straightaway, bug 21639
    If the phone box has a '-' and not a checkbox:
    sudo koha-mysql kohadev
    INSERT INTO message_transports (message_attribute_id,message_transport_type,is_digest,letter_module,letter_code) VALUES (4,'phone',0,'reserves','HOLD');
 5 - Place a hold for the patron
 6 - Check it in and confirm the hold to set it waiting
 7 - sudo koha-shell kohadev
 8 - perl misc/cronjobs/thirdparty/TalkingTech_itiva_outbound.pl --type=RESERVE -w 0 -v
 9 - Note the Output says it will be on STDOUT, but nothing is output
10 - Apply patch
11 - repeat
12 - Hold info is output to command line
