Bug 32624: Don't include guarantee or guarantor fines in BV (fines amount) in SIP messages

This patch chanegs the code to report only the patron's personal fines, and to report a block
from other fines in the screen message

This is to prevent overpayment on accounts from SIP machines

To test:
1 - prove t/db_dependent/SIP/Patron.t
