update foundname when detecting a zonecut above qname

Browse Source 
an assertion could be triggered in the QPDB cache if a DNAME
was found above a queried NS, because the 'foundname' value was
not correctly updated to point to the zone cut.

the same mistake existed in qpzone and has been fixed there as well.
