==Background
When anonymous and non logged in users disable Page Previews, they see a second screen explaining that a link is added to the footer where they can re-enable. In {T277639} we will create a joint pop up for this user group to display all Pop-ups types in one pop up, and will adjust the behaviour of the link in this ticket.
==Requirements
[] After an anonymous user or a user that is not logged in clicks on the cog wheel and then disables either the Page previews or Reference previews, or both settings, users see the same graphic and message about re-enabling in the footer (with an adjusted header, "Previews")
[] If any of the previews are disabled, a link to re-enable previews is added to the footer - using the existing link for page previews already labelled "Enable previews"
[] Use current behavior of Page Previews flow: when clicking "Enable previews", the pop-up comes back with the previously set settings and the user can change their setting for any preview type. If they leave it unchecked and click save again, do not show the graphic about the footer.
==Mocks
**Note: the header of the pop-up should be "Previews" as above (mock has not been updated)**
