Respect -dns flag when -https is enabled

This change makes the `-dns` flag be respected with the `-https` flag

Before this change the `sudo hyperfox -ui -http 80 -dns 8.8.8.8` -> `curl http://example.com` lead to an infinite
request loop when `-https` was also supplied (i.e. `sudo hyperfox -ui -http 80 -https 443 -dns 8.8.8.8`).
