BUG/MEDIUM: http-htx: Loop on full host value during scheme based normalization

During scheme based normalization, when the authority is normalized, the
host headers are updated accordingly. Only full host header values must be
updated. Comma-separated list are not expected here.

It is important to do so to be consistant with other places where the host
header is updated (when the request URI is changed for instance).
