Fix HiveQuerySuite?

Every time we called TestHive.reset() we created a new temp
directory for derby, and then we would go ahead and override
the old one in the same TestHiveContext. This fails tests that
use multiple sessions for some reason. Setting the same confs
in metadataHive whenever we call reset() seems unnecessary,
so I removed it.
