[epiphany/wip/exalm/fullscreen] action-bar-start: Hide new tab button in fullscreen

    action-bar-start: Hide new tab button in fullscreen
    
    Ideally, there is a tab bar in fullscreen. However, since we don't have
    that, hide the button instead. This still leaves shortcuts though.
    
    Update the incognito style not to assume only the stack is .titlebar.
