Setting DISABLE_HTTPS without SSL_CERTIFICATE_GENERATION doesn't start

[chmac]

Firstly, thanks a lot for this repo. It really makes running zulip a breeze. 🧡

I tried adding DISABLE_HTTPS: "True" to my compose file as I want to run zulip behind a reverse proxy. But I got stuck in a boot loop. It would complain about the SSL certificates not existing, and then say certificate creation failed.

I tried setting SSL_CERTIFICATE_GENERATION: "False". I think this generated slightly different log messages, but still ended up in a loop without the server starting.

Finally I set SSL_CERTIFICATE_GENERATION: "self-signed" and now the server starts, and the logs look like it generated a certificate, even though the logs also say that https was disabled.
