Can't set up WSS / TLS in 0.8.13 - AttributeError: 'CentralSystemSettings' object has no attribute 'certfile'

[BJReplay]

Describe the bug
I set up your repo as a custom HACS repo, and installed 0.8.3 to test adding two chargers - one that I had installed today, and a simulator that I was using to tune automations for when the charger arrived.

As my charger supports wss, I removed the central station and charger, and attempted to re-set up the central station with TLS / WSS.

I have the certificates mounted to a mount (/certs) in the HA docker container, and specified them as /certs/fulchain.cer and /certs/my.cert.key

However, I couldn't set up the central station using WSS / TLS (i.e. with the TLS box ticked), and the error shown below was logged on each attempt. If I didn't specify TLS, I could set it up.

I reverted to the HACS repo (removed your repo as custom repo), and re-downloaded 0.7.0, and was able to set up WSS / TLS as expected.

To Reproduce
Steps to reproduce the behavior:

1. Remove any existing central stations and chargers.
2. Ensure that certificates are available (i.e. copied to config / in a mount point).
3. Attempt to set up a central station leaving all items default except for TLS ticked on, and specifying the certificates.
4. See error - failed to set up service.
5. Note log errors.

Expected behavior
TLS should be able to be specified.
