This isn't a recent change, see [1]. I presume Amazon is most likely
still broken in Epiphany (when these roots are removed) as there's been
no action on [1], where we decided that gnutls-cli accepted
www.amazon.com because it uses certs if they're valid for either email
or TLS, whereas GLib only uses certs if they're valid for TLS.

Note that due to CDN magic, sites like Amazon load lots of subresources
like images and CSS over connections using unrelated certs, so a more
reliable test is to actually open the web page in a browser.

P.S. To both Kai and Nikos: thanks for all your effort on this matter. A
couple months ago I was quite worried, but now I expect things will turn
out fine.
