Bugfix: Require OrderedTxItems to provide properly scoped accounting entry list

OrderedTxItems returns a multimap of pointers, but needs a place to store the actual CAccountingEntries it points to.
It had been using a stack item, which was clobbered as soon as it returned, resulting in undefined behaviour.
This fixes at least bug #1768.
