[Feature Request] Turning off base emissions in GCHP fails

[lizziel]

I just ran into this issue so am making a note of it to look at later. I think turning off base emissions is primarily useful for GCST testing so am putting this issue here rather than the main GEOS-Chem repo.

The model crashes when running GCHP benchmark simulation with base emissions turned off within runConfig.sh. This is the end of the log:

I have not tested in GC-Classic.
