    messageTray: Remove transient sources
    
    As far as I can tell, the only behavior change of a transient source
    is that they auto-destroy after viewing their summary box pointer.
    Since all transient sources are only associated with transient
    notifications, it seems that we can never get to their summary box
    pointer in the first place! Remove support for this.
