norikra-client doesn't show command name in Error & Usage messages

[Mahito]

norikra-client shows error & usage massages when gets wrong command.
It doesn't include command name.

This examples lost "admin" and "query".

% norikra-client admin stats hoge
ERROR: "norikra-client stats" was called with arguments ["hoge"]
Usage: "norikra-client stats"

% norikra-client query add hoge
ERROR: "norikra-client add" was called with arguments ["hoge"]
Usage: "norikra-client add QUERY_NAME QUERY_EXPRESSION"

I expect to get "norikra-client admin stats" or "norikra-client query add".

Thanks.
