Use HTTPS as a default scheme

HTTP was a good default some time ago. But now most of the websites are moving to HTTPS and also modern browsers like Chrome, Firefox, Edge, Opera, etc. are defaulting urls without scheme to HTTPS (e.g. "//example.com" will get defaulted to "https://example.com"). So I think it makes more sense now to use HTTPS instead HTTP as a default.
