Ticket #47534 - RUV tombstone search with scope "one" doesn`t work

Bug description: slapi_sdn_scope_test_ext examines the given dn
satisfies the scope against the base dn.  Onelevel case for the
tombstone DN ignores the nsuniqueid leaf rdn before checking the
scope which should not be done for the RUV tombstone.

Fix description: This patch correctly handles the RUV tombstone
as an exception.
