Title: HPCC-8413 Fix problems with STEPPED JOIN accessing non existant results

A stepped join tries to prevent the inputs from creating splitters - since that
will default the smart stepping on indexes. However if the inputs were not
indexesw then it could generate an internal error since one part of the graph
assumed a spill would be created, but none ever was.
