CAM FXHIST tests that fail

### Brief summary of bug

In ctsm5.3.059 these two tests fail:

ERS_Ld3.f19_f19_mg17.FXHIST.derecho_intel.cam-waccmx_weimer (SETUP)
SMS_D_Ln9.f19_f19_mg17.FXHIST.derecho_intel.cam-outfrq9s_amie (SETUP)

I think the issue has to do with the RUN_STARTDATES that are choosen.
We have some testmods for waccmx type testing that probably need to be updated

### General bug information

**CTSM version you are using:** ctsm5.3.058-93-gb96596982 (will be ctsm5.3.059)

**Does this bug cause significantly incorrect results in the model's science?** No

**Configurations affected:** Seems to occur for f19 cases at non standard RUN_STARTDATE times

### Details of bug

### Important details of your setup / configuration so we can reproduce the bug

The config files for each case looks like this:

```
cat shell_commands
./xmlchange --force RUN_STARTDATE=2005-12-31
./xmlchange --force ROF_NCPL=\$ATM_NCPL
cases/ERS_Ld3.f19_f19_mg17.FXHIST.derecho_intel.cam-waccmx_weimer.GC.ctsm5358testdelist> cat user_nl_cpl
reprosum_diffmax=1.0e-14
reprosum_recompute=.true.
```

```
cat shell_commands
./xmlchange --force ROF_NCPL=\$ATM_NCPL
./xmlchange --force GLC_NCPL=\$ATM_NCPL
./xmlchange --force RUN_STARTDATE=2003-10-28
```

### Important output or errors that show the problem

Fails in preview_namelist step like this:

```
If an old case build already exists, might want to run 'case.build --clean' before building
You can now run './preview_run' to get more info on how your case will be run
