fw/entrypoint: make command mandatory for Python 3

Browse Source 
Python 3 has changed the behavior of subparsers so that they are no
longer mandatory by default. As a result, executing just "wa" under
Python 3 results in a random error, rather than a help message.

Fix this by making the subparsers mandatory.
