Bug 17588: Koha::Patrons - Move GetMemberIssuesAndFines

The GetMemberIssuesAndFines subroutine used to retrieve the issues,
overdues and fines for a given patron. Most of the time, only 1 or 2 of
these values were used.
This patch removes this subroutine and uses the new get_issues,
get_overdues and get_balance method from Koha::Patron and Koha::Account::Lines.

Test plan:
1/ Add overdues, issues and fines to different patrons
2/ On the checkout, checkin and patron search result and the patron
detail pages, these 3 informations, if displayed before this patch, must be
correctly displayed.
3/ Use the batch patron deletion tool and make sure that patrons with a
balance > 0 are not deleted
