Need to get the nidmap so that the apps have something to look at for wireup.

Without this we get errors like the following since the nidmap is empty in the apps:
[[13094,1],1] ORTE_ERROR_LOG: Not found in file ess_env_module.c at line 234
[[13094,1],1] ORTE_ERROR_LOG: Not found in file ess_env_module.c at line 281

This commit was SVN r23536.
