Pass correct TupDesc to ri_NullCheck() in Assert
Previous coding was passing the wrong table's tuple descriptor, which
accidentally fails to fail because no existing test case exercises a
foreign key in which the referenced attributes are further to the right
of the referencing attributes.
Add a test so that further breakage is visible.
This got broken in 16828d5c0273.
