Bug 29380: Correct table name in joins to prevent errors

The commit "Bug 29290: Rename relationships borrower =>
patron" (d46492ac23) renamed the relation for the borrowers table from
'borrower' to 'patron' but the joins were not updated accordingly so a
few scripts got broken.

To test:
 1) Notice that
    $ perl misc/cronjobs/automatic_renewals.pl -c -s -v
    returns 255 error code on exit
 2) Apply patch
 3) Notice the automatic_renewals.pl works now and exit code is 0
 4) Make sure /cgi-bin/koha/tools/batch_extend_due_dates.pl works.
 5) Try to grep for 'borrower' in Koha source code and see if there
    are any other join done using the Koha::Checkout or
    Koha::Old::Checkout objects.
