We'll handle this just like when the user selects a non-friend: we'll just open the chat directly.
We we want to treat this case similarly to when the viewer selects a non-friend: instead of letting them include themselves in the list, we will just open directly to the `PRIVATE` if the user select themselves at the start (this diff), and not list them as an option if they select somebody else at the start (D13543).
