Bug 26703: (follow-up) corrected aqbudgets title

Corrected the admin/aqbudgets file so that the page title displays
correctly.

To test:
1) Go to staff client
2) Go to admins module
3) Go to aqbudgets page
4) Check that the page title is "Funds > Administration > Koha"
5) Check that when modifying a fund the page title is "Modify Fund > Funds > Administration > Koha" or "Modify Fund [Fund Name] > Funds > Administration > Koha"
6) Check that when adding a fund the page title is "Add Fund > Funds > Administration > Koha"
