  Log Message:
  -----------
  Fix leaking of change listeners (MID-5355)

When AssociationSearchExpressionEvaluatorCache was entered twice,
two invalidators for it were created and registered (by mistake).
Upon exiting the cache, only one of them was unregistered, because
the reference to the other one was already lost at that moment.
