    clipboard-rdp: Don't leak the MimeTypeTables
    
    When the RDP client sends a new FormatList, but the session already
    stopped, then gnome-remote-desktop drops the FormatList.
    However, gnome-remote-desktop already prepared the MimeTypeTables for
    the update. These are currently leaked.
    
    So when the session already stopped, but gnome-remote-desktop still got
    a new FormatList, free the MimeTypeTables to prevent a memory leak.
