Bug 23767: Include child funds in total spent and ordered on acqui-home

To test:
 1 - Have three funds, two parents and one child
 2 - Open a basket and add an order to each fund
 3 - View acqui-home.pl
 4 - Note that ordered values are only added from the two parent funds
 5 - Complete these orders (close basket, receive)
 6 - Note the spent only includes parent funds
 7 - Place three more orders, one from each fund
 8 - Now you can see both spent and ordered are incorrect
 9 - Apply patch
10 - Reload, all should add correctly
