How to remove "online accounts" from "system settings"?

I uninstalled "Unity" and use "Gnome Shell" instead, but the new "online accounts" was still in the "system settings" menu. How can I completely remove it?

I tried the command below but it doesn't work:

sudo apt-get -y remove unity-lens-shopping account-plugin-aim account-plugin-facebook account-plugin-flickr account-plugin-google account-plugin-icons account-plugin-identica account-plugin-jabber account-plugin-salut account-plugin-twitter account-plugin-windows-live account-plugin-yahoo gnome-online-accounts 

If you want to remove the option in gnome-control-center simply execute :

sudo apt-get purge unity-control-center-signon

And you will see online accounts disappear from system settings (if you're using Unity).
