[gnome-mud] connection-view: Don't read freed encoding

    connection-view: Don't read freed encoding
    
    Encoding was sometimes incorrectly freed, you can reproduce it by
    connecting to a MUD, which causes remote_encode to be set, then
    disconnecting and reconnecting. Valgrind will show the read.
