[baobab] Check for duplicates before adding a volume

[Stefano Facchini <sfacchini src gnome org>]

    Check for duplicates before adding a volume
    
    Since GVolumeMonitor unnecessarly fires "volume-added" signals
    at startup (see bugzilla bug 684677) we need to workaround and
    check for duplicates, until a fixed version of gvfs is released.
