    ESourceRefresh: Handle "notify" signals from an idle callback.
    
    ESourceRefresh runs e_source_refresh_force_timeout() in response to its
    ESource becoming enabled.  The problem is "GObject::notify" signals can
    be emitted from any thread.
    
    Schedule an idle callback on the ESource's GMainContext to call
    e_source_refresh_force_timeout(), rather than calling it directly from
    the "GObject::notify" signal handler.
