Fix bug for new --list --format options when no default journal is specified (#1621)

* rename test config

* Change journal name validation

Journal name validation used to happen before postconfig commands could
have a chance to run, so now each command is responsible for its own
error-checking of the journal name.

Added a new decorator and function that makes this error-checking easier.

* fix wrapper function call to be more like original

* change arg names to show which aren't used

* add type hints
