 Annotating across multiple tables results in wrong answers. i.e.

 In [110]: total =
 Branch.objects.all().annotate(total=Sum('center__client__loan__amount'))

 In [111]: total[0].total
 Out[111]: 3433000

 In [112]: repaid =
 
Branch.objects.all().annotate(repaid=Sum('center__client__loan__payment_schedule__payments__principal'))

 In [113]: repaid[0].repaid
 Out[113]: 1976320.0

 In [114]: both =
 
Branch.objects.all().annotate(total=Sum('center__client__loan__amount'),repaid=Sum('center__client__loan__payment_schedule__payments__principal'))

 In [115]: both[0].repaid
 Out[115]: 1976320.0

 In [116]: both[0].total
 Out[116]: 98816000
           ^^^^^^^^^^^

 Compare the output of total in 116 vs. 111 (the correct answer).
