[rules-dev] Property reactive broken in 5.5.0 Final

package reactive;

declare Person
@propertyReactive
   name   : String
   age    : int
   weight : int
   city   : String
end
This is a simple all-DRL test case demonstrating that property reactive
may cause pending activations to be removed, depending on some
specific composition of the LHS.

* As the DRL is, only one rule fires but both should.
* Adding the Integer pattern (in either form) in both rules may result in
   both rules firing, or only one, but both should.
