Revert some changes from the INTERSECT/EXPECT patch that broke

rule system semantics by having Var nodes referenced across multiple
parsetrees when rules split them.
Added more tests to the rules regression test.
The code in question resulted from v6.3 based development and was
a little careless applied to the v6.5 source tree.

qualification expression trees in the execution state. Prevents from
