homme::compute_tendencies failes for qc and qi

The core issue is that homme does not explicitly list qi/qc as updated fields. But since they are subfields of the updated group "tracers", we should be able to compute tendencies. So this is not a homme problem, but more of an AtmosphereProcess class problem, where the tendency calculation fcn needs to be expanded a bit.

It's still a bug tho
