HPCC-12515 no_datasetfromrow should always traverse input

Is 'query' the correct semantics for a 'doGet' routine? 

I would have thought that doGetGraphLocalisation was aptly prefixed due to this line that it contains.
 expr->setTransformExtraOwned(getSizetConstant((unsigned)ret)); ( I did't check that this was suitably named though)

In which case it doesn't look like a query.
