cubicweb #3376322 req.base_url(secure=True) is broken if no https-url is defined in config [validation pending]

Because of https://www.cubicweb.org/revision/2519559.

If there's no https-url in config, self.vreg.config.get('https-url) returns None, so the default value in the above patch is not used.
