Non-regression of feature/wmputman/developJune09_L91 branch

We were asked to determine why when using this branch:
feature/wmputman/developJune09_L91
the GEOSgcm.x does not pass regression test. Running with the debugging option quickly revealed that there is an unitialized variable (PTYPE) as the code crashes here:
https://github.com/GEOS-ESM/GEOSgcm_GridComp/blob/feature/wmputman%2FdevelopJune09_L91/GEOSagcm_GridComp/GEOSphysics_GridComp/GEOSmoist_GridComp/GEOS_MoistGridComp.F90#L12556

If one looks PTYPE is used here but only set if DIAGNOSE_PRECIP_TYPE: TRUE but the default and what everyone has been using is this set to FALSE. If this is false PTYPE is used multiple places with no protection and results in a crash if using the debugging flags or just the non-regression in the optimized build. This needs to be cleaned up so PTYPE is protected from use if it was not filled.
