Update qp unit tests merging denial and zone data

Update qp unit tests merging denial and zone data

If zone and denial data are going to be stored in the same qp storage,
the unit tests need to be updated to reflect this change. The code
changes mainly affect name to qpkey conversion, lookups, and
predecessors.

A note on predecessors: since the denial and zone data are now in the
same qp storage, the predecessor of the first name in the zone data will
consequently be the last name in the denial data.
