Bug 21282: Sync ordered and spent values with acqui home

Bug 21282: Sync ordered and spent values with acqui home

The order list for each fund calculates using the ecost tax excl., but
it should be tax incl.
At the moment this means that the sum on the start page table and the
order list don't match up.

Test plan:
- Create and receive orders
- Values on acqui home and ordered/spent should be the same
