ADQL: Use addMatch(...) function also for the root search object in SimpleSearchHandler.

Becareful with the function addMatch(ADQLObject, ADQLIterator): the iterator may be null if the match to add is the root search object itself!
No modification needed in SimpleReplaceHandler: Null test already done :-) !
