Makes filter button works in UI.

To have correct stat method, the following scripts in erp5_accounting have to be modified:
AccountingTransactionModule_zGetAccountingTransactionList
Resource_zStatInventory
AccountModule_statAccountingTransactionCount
AccountModule_statTotalSourceDebit
AccountModule_statTotalSourceCredit
AccountModule_statBalance

They have been fixed in nexedi ERP5 and will be released with the next erp5_accounting buisness template.
