    web-view: stop setting background color
    
    With WebKitGTK 2.26.4, it's now finally possibly to use dark GTK themes
    without horribly breaking the web, since
    https://trac.webkit.org/r255342. At long last!
    
    Problem is, Epiphany breaks this badly by setting the view's background
    color from the system theme. We cannot use dark background color by
    default. This results in dark text on dark background. See
    https://bugs.webkit.org/show_bug.cgi?id=206953 for details.
    
    This will reintroduce #960, so we'll need to reopen that when this
    lands.
