Bug 17135 - Some minor changes & fixes in the script

- all non-fatal output redirected to STDOUT (as there is an intention
to run this script from updatedatabase.pl)

- added borrowernumber and itemnumber equality checks to the SELECT
statement in getFinesForChecking() - accountlines.issue_id alone is not
entirely trustworthy (because InnoDB forgets it's highest auto_increment
after server restart), in some rare cases it may point to some random
issue for different patron and different item
