The next patch will move C4::Circulation::AnonymiseIssueHistory and
C4::Members::GetBorrowersWithIssuesHistoryOlderThan to Koha::Patrons
This patch move the history anonymisation code to the Patrons.t test
file and the entire subtest related to StoreLastBorrower to
StoreLastBorrower.t
It just moves and add some minor adjustements.
