Don't send or create a new connection request if you're already connected
Created by: zzottel
Adding more detail as I just stumbled over the thread in the Grid that was the reason for this bug report:
A member had used an old export of his channel to recreate it at another host. Not all his current connections were in that export, so he started reconnecting to his old connections. This lead to new connection requests being shown at his connections, although in their view, they were still connected to the member.
