Fixed bug #28188: performance degradation for outer join queries to which
'not exists' optimization is applied.
In fact 'not exists' optimization did not work anymore after the patch
introducing the evaluate_join_record function had been applied.
Corrected the evaluate_join_record function to respect the 'not_exists'
optimization.
