    [1836] also added unittest that would fail the fixed in this branch.
    
    To make this test workable, I needed to change the returned flag
    for the NXRRSET case in MockZoneFinder::find() from setting NSEC_SIGNED
    unconditionally to setting any SIGNED flags.  this doesn't affect other
    tests.

    [1836] added a lettuce test case for delegation from unsigned zone with DO bit.
    
    this would identify the bug fixed in this branch.

    [1836] throw exception from addDS only when the find result != NXRRSET.
    
    Otherwise, queries with DO bit can incorrectly trigger an exception if
    the zone is unsigned and queyr result is delegation.
