run_cmake_test crashes when finding prnc input files

[mickaelaccensi]

Describe the bug
run_cmake_test crash and looking for input files for ww3_prnc if the configuration is expected to have input file with the suffix of the gridset

To Reproduce
run_test -f -N -S -T -s MPI -s NO_PDLIB -w work_ma -m grdset_a -f -p mpiexec.hydra -n 28 ../model ww3_tp2.21

Expected behavior
in run_cmake_test, we need to improve in that way :

        if [ $nml_input ] && [ ! -z "`ls ${path_i}/${prog}${gu}*.nml 2>/dev/null`" ]
        then
          inputs_tmp="`ls ${path_i}/${prog}${gu}*.nml 2>/dev/null`"
         else
          inputs_tmp="`ls ${path_i}/${prog}${gu}*.inp 2>/dev/null`"
        fi
