Fixes an issue with canReflect.onValue
// oldVal was passed to the change event callback as expected
compute.on("change", function(newVal, oldVall) {
// oldVal was being set correctly here
});
// but it was always undefined when using canReflect.onValue
canReflect.onValue(compute, function(newVal, oldVal) {
// oldVal always `undefined`
});
