balance non-deferral accounts is broken with non-view parent accounts
I just tried to run the wizard and have encountered the following problem: I have multiple 646X accounts with a negative balance (that needs to be zeroed) but their parent account (646) is not a view. Unfortunately when you run the wizard, it will correctly zero the 646X accounts but it will also try to zero the total of all 646X accounts in the 646 account (which in fact already had a zero balance). So you end up with a wrong result at the end.
This is probably related to the fact that tryton tends to display the total of the sub-accounts in parents accounts... this is visible in the income statement and in many other views. I have always found this intermediary total to be misleading when used on non-view accounts (but I can understand that it is also useful at times).
