Agents window on the "server" will list other remote sessions

1. start up the agents window on two remote machines and allow remote connections on both
2. on the local machine connect to those two remotes
3. go back to a remote machine with remote desktop and look at the listed sessions

:bug: sessions from the other remote are sometimes listed, even though I never asked it to connect from that machine

This crowds up the list on that machine when I am there to specifically to work on the sessions that are local to that remote. There also isn't an obvious way to drop those sessions from the list, and if that will cause it to disconnect everywhere.
