reject invalid `role:target` early in sender rpc handler about iris HOT 2 CLOSED

I can't reproduce this. When I try to send to an invalid user using iris.client, I get this:

ValueError: Error response from server, 400: {
    "title": "Request rejected by sender",
    "description": "INVALID role:target"
}

However, I did add tests and more logging to confirm this behavior, and added a few more checks that reject requests that are missing both body and template (which results in not being able to send a message anyway):

Ha, you are right, I missed that extra expand check ;)
