WebSocket code has same incorrect server certificate verification logic as em-http-request

[lawrence-forooghian]

The issue described in #396 also exists in our WebSocket code (although it's not currently causing a test failure since we don’t use Let’s Encrypt on our WebSocket endpoint). Fix it.

Seems similar issue was patched as a part of #234

I might be missing something but I think that #234 just pulls in the verification logic from em-http-request, i.e. the incorrect logic described in #396?
