bug: Message extra parameters are passed to init

[nicola-lunghi]

I have the following code:

async def my_func():
    payload = '{"jsonrpc":"2.0","method":"connect", "arguments": ["wifi_c8df844b53ae_62756d626c656265652d323539373835_managed_psk"], "id":"aaaaaaqvjcYf5A0h"}'
        response = await jrpc_dispatch(payload.decode(), debug=True)

@method
async def connect():
    # do something

here I use wrongly "arguments" for the argument list

I got the exception

my_test[1101]: ERROR: Task exception was never retrieved
my_test[1101]: future: <Task finished coro=<process_rpc_message() done, defined at /usr/lib/python3.7/site-packages/test_mqtt/mqttrpc.py:12> exception=TypeError("__init__() got an unexpected keyword argument 'arguments'")> [asyncio:default_exception_handler:1615]

~This seems correct to me, what are you expecting to happen?~

Ok it should return a JSON-RPC error, not raise an exception -- fixed by @deptyped in #128 .
