I have a built-in web-server running on 0.0.0.0:8000 which I've launch with the following command:

bin/console server:start 0.0.0.0

When I try to get it's status with the following command, it doesn't work:

bin/console server:status 0.0.0.0

# I receive that error message
# [WARNING] No web server is listening on http://0.0.0.0

But if I try the following command, it works:

bin/console server:status 0.0.0.0:8000

# I receive that message
# [OK] Web server listening on http://0.0.0.0:8000

I think, that the command should work like the others and use the default port if none is specified.
