Disable assertion failing for lambdacalc, related to proper parent match tracking

Problem lies in that journal doesn't track all justifications
for reactivated occurrences. For a parent of such occurrence
its original activating match is considered, while
justifications from the Reactivating match aren't tracked.
So, this information about immediate reactivating parent is lost.

lambdacalc lang typesystem heavily uses reactivation, so it fails.
