Fix two CloneNonCycle issues
CloneNonCycle() tries to detect cyclic object references without copying
them. There are two issues:
-- for elements in an array or a dictionary, they should be able to
refer to the same object, which are not cyclic;
-- for cyclic referenced elements in an array or a dictionary, do not
clone the element at all. Having nullptr or <key, nullptr> as an element,
like we did before, might cause crash when the element being accessed.
