Fix trigger WHEN conditions when both BEFORE and AFTER triggers exist.

Due to tuple-slot mismanagement, evaluation of WHEN conditions for AFTER
ROW UPDATE triggers could crash if there had been a BEFORE ROW trigger
fired for the same update.  Fix by not trying to overload the use of
estate->es_trig_tuple_slot.  Per report from Yoran Heling.

Back-patch to 9.0, when trigger WHEN conditions were introduced.
