Fix for "section bank account" select being empty on reports dialogs and payment transaction

Section bank account item list script was using parent_strict_group_uid related key but in 772033ed we removed parent_strict_group_uid related key and added support to generate strict_parent_group_uid related key.

In that case, Section Bank Account field on payment transaction was empty

The TypeError: Unknown columns ['parent_strict_group_uid'] was only in the log files, because we are still ignoring errors in TALES.

I'm adding tests to cover this script, it's logic should have been tested anyway.
