On no-batch systems, short-term archiver runs even if the run fails

@adrifoster pointed this out and I have reproduced it: On our macs, the short-term archiver runs even when the run fails. My guess is that this is due to this being a no-batch system and that the logic for stopping the short-term archiver from running doesn't work correctly in the absence of a batch system.

I reproduced this from CTSM (ctsm5.1.dev120, which uses cime6.0.100) by introducing an endrun call. The CaseStatus file shows:

This is **not** high priority from our perspective, but we still wanted to open an issue documenting this.
