Modified CI testing to use different container names for the srun/rshlaunch vs. SPANK jobs. While this didn't make any difference for GitHub Actions, using the same names prevented running these jobs simultaneously when running the CI locally through |

The commpath branch gets rid of location. Changing args.location to args.commpath should work, but I'd want to test that out. If your PR goes in first, I can update this in the commpath branch.
