Node fails to start if relay-chain-rpc-urls is set.

How to reproduce:

docker run -it --rm mythicalgamesengineering/parity:v1.13.3 /usr/bin/mythos-node   --chain=muse --relay-chain-rpc-urls "wss://rococo-rpc.polkadot.io" --detailed-log-output -l reconnecting-websocket-client=debug

Install ca certs inside docker container

RUN apt-get update && apt-get install -y ca-certificates && rm -rf /var/lib/apt/lists/*
