Simple chem treated as finite rate

[rmcdermo]

@drjfloyd Looks like we need to clean up some logic in read after the chem commit. I picked one of the simple cases to run, fds/Verification/Fires/fire_const_gamma.fds and I get this:

ERROR(XXX): REAC 1. Tracked species AIR used in a finite rate reaction without N_S defined is not a primitive species. (CHID: fire_const_gamma)

I have for now just commented out the error check.
