correctly update input file using initial_models (#2970)

previously I didn't properly use initial_model to generate this input file which is used for NSE stuff. Now this is done correctly by using inputs.M_WD-1.1.M_He-0.05.CO in initial_model/sub_chandra with NETWORK_DIR=subch_base

Exec/science/subchandra/GNUmakefile.nse_net
