resolved: refuse sending packets to our own stub listeners
A previous commit made sure that when one of our own packets is looped
back to us, we ignore it. But let's go one step further, and refuse
operation if we notice the server we talk to is our own. This way we
won't generate unnecessary traffic and can return a cleaner error.
Fixes: #17413
