Compatibility wrapper oldToNewDescriptionItem returns error when value exists

[Scott-Cam]

In cw.php oldToNewDescriptionItem checks the input array for the value using findValueInArray and then checks (!$dsData) if the value was found. However findValueInArray returns null on error and any other value should be valid, but checking !$dsData will return errors for such things as empty arrays. I think this should be changed to an explicit check for null $daData===null.
