incorrect sum of split transaction entered via template x2

[Yaroslav]

Initial conditions:
1. Account 'Cash' exists
2. Account 'Visa' exists
3. split transaction template exists for 'cash withdrawal':
      1) transfer from Visa to Cash: sum=100
      2) transaction for bank fee: sum= 1
    Total for split: sum=101.0

Scenario:
1. open Visa account
2. open Templates dialog
3. Tap on green "+" to get x2 and tap appropriate template
4. New split transaction has been added.
Expected:
   1) Visa decreased by 200 (transfer)
   2) Visa decreased by 2 (bank fee)
   3) Cash increased by 200
Actual:
   1) Visa decreased correctly (both transfer and fee)
   2) Cash increased only by 100 (the same for x3, x4 and more)

5. Edit the split transaction added at step 4, open and save "child" transfer and then save "parent" transaction.
    After that Cash account increased correctly.
