Letter case mismatch with phenix config create/delete

[JamieThorpe06]

When creating a scenario config (e.g., phenix config create /path/to/scenario.yml), the command line output capitalizes the word "Scenario". If you look at the config list (phenix config list), the word "Scenario" is also capitalized. However, if you then try to delete the scenario with phenix config delete Scenario/test with capitalized "Scenario", there is an error. The "delete" command expects the word "scenario" to be all lowercase. I think this command should either be case insensitive or that the cases should be consistent between the "create" and "delete" commands.

The same error can be seen with topology configs.
