Add regression tests exercising the non-hashed code paths in nodeSetop.c.

Add regression tests exercising the non-hashed code paths in nodeSetop.c. Perusal of the code coverage report shows that the existing regression test cases for INTERSECT and EXCEPT seemingly all prefer the SETOP_HASHED implementation. Add some test cases in which we force use of the SETOP_SORTED mode.
