Port proto_nd_flow yaml changes to ndlar_flow yamls

When running the nominal ndlar_flow workflow for NDLAr in develop, Eva Sabater came across the following crash:

~~~ RUN ~~~

This PR implements @mjkramer's suggestion for a fix.

Tested at small scale and now larger scale, nominal NDLAr workflow now running all the way to the end.
