[epiphany/wip/sync: 13/16] sync-service: Connect the GSettings signal to handle changed sync frequency

[Gabriel Ivașcu <gabrielivascu src gnome org>]

    sync-service: Connect the GSettings signal to handle changed sync frequency
    
    We don't need to trigger the signal when closing the preferences dialog
    because we don't really care if the sync is rescheduled with the same
    frequency.
