[epiphany/gnome-3-30] embed-shell: Use more g_signal_connect_object()

    embed-shell: Use more g_signal_connect_object()
    
    I just hit a crash where a history service callback executes improperly
    after the EphyEmbedShell has been destroyed. Certainly not supposed to
    happen. Make sure this never happens.
