Fix logistic network stats for the 2.0 api

`get_contents` and `targeted_items_pickup`/`_deliver` return lists of
ItemWithQualityCount in 2.0, they are no longer name keyed dictionaries,
so the logistorage stats were indexing by array position.

PreferenceEnum is bidirectional, matching what ExpUtil.enum returns.
