rpc_command hook passes wrong payload

[fiatjaf]

According to the documentation (and the standard from other hooks) rpc_command should pass the following payload to the plugin:

{
    "rpc_command": {
        "id": 3,
        "method": "method_name",
        "params": {
            "param_1": [],
            "param_2": {},
            "param_n": "",
        }
    }
}

However what they do send is

{
    "rpc_command": {
        "rpc_command": {
            "id": 3,
            "method": "method_name",
            "params": {
                "param_1": [],
                "param_2": {},
                "param_n": "",
            }
        }
    }
}
