v1.2.4 - Fix logging for command function calls

In addition to argparse-related calls, function invocations for @arguably.command are now also logged. This can be seen if using python3 -m arguably --debug your_script.py, or if you set up logging in your script that utilizes arguably.

This was intended behavior from the start, but was not implemented.
