[IMP] account: speedup of the aged partner balance

Removed a browse on partners made in a loop, for a substantial gain of time and DB queries.

Observed gain for a real data DB with 500 partners to print in the aged report:
time (ms)                  # queries
Before patch               4583                       1623
After patch                2932                        553
Gain                       1651 (36%)                 1070 (66%)
