Subject: [PATCH] Bug 12168: fix spent and ordered budget values are wrong when
 depth >= 2

A really weird (and old) code process the calculation for the spent and
ordered sublevel funds.

It only takes into account the direct children.

So if you have:
fund1 (spent=100) parent of fund11 (spent=10) parent of fund111 (spent=1),
you get:

fund     | base-level | total spent
fund1    | 100        | 110
fund11   | 10         | 11
fund111  | 1          | 1

which is wrong, it should be

fund     | base-level | total spent
fund1    | 100        | 111
fund11   | 10         | 11
fund111  | 1          | 1

Test plan:
- Create 1 budget and 3 funds with the same structure as above.
- Create some orders and receive them (not all).
- Go on the fund list view and verify the values are correct.
