Enable to define empty TLS option by flag for Let's Encrypt

[Slashgear]

I wanted to configure traefik for my project only by flags, in order to limit my configuration file to a simple docker-compose.
This is an extract of my docker-compose file.

service-front:
labels:
- "traefik.backend=front"
- "traefik.port=80"
- "traefik.frontend.rule=Host:domain.com"
- "traefik.frontend.entryPoints=http,https"
image: kebuu/zenquizz-front:dev
traefik:
image: traefik
command: --web --docker --acme --acme.domains=domain.com --acme.email=test@traefik.io --entryPoints='Name:http Address::80 Redirect.EntryPoint:https' --entryPoints='Name:https Address::443 TLS' --acme.storagefile=acme.json --docker.domain=localhost --logLevel=DEBUG
ports:
- "80:80"
- "443:443"
- "8080:8080"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /dev/null:/traefik.toml
- /opt/acme/acme.json:/acme.json
labels:
- "traefik.enable=false"

In my logs I could see that TLS option was not set:

"https":{"Network":"","Address":":443","TLS":null,"Redirect":null}}
