reachableroots: fix transposition of set and list types in PyArg_ParseTuple
This is being masked by the function not properly returning NULL when
it raises an exception, so the client code was just falling back to
the native codepath when it got None back. A future change removes all
reason for this C function to return None, which exposed this problem
during development.
