    user-menu: Keep track of current presence
    
    We keep track of presence changes by connecting to the
    Tp.AccountManager:most-available-presence-changed signal.
    However, if multiple accounts are in use, telepathy may
    lie to us and emit the signal even when the most available
    presence is unchanged.
    Work around this by keeping track of the current presence
    ourselves.
