[TASK] Prevent superfluous filters in DataMapProcessor

For consistency in the filterNumericIds method of DataMapProcessor,
there should only be one result be returned. This patch removes the
second parameter to invert the methods behaviour.

Back-porting to TYPO3 v9.5 as well, for code consistency.
