uv_read_start: Assertion `((stream)->io_watcher.fd) >= 0' failed.

Test case (non-minimal): https://travis-ci.org/Tennu/tennu/builds/89144586

Affects versions 4.2.1 and 5.0.0. Not sure about older versions.

Minimal test case:

const TlsSocket = require('tls').TLSSocket;
const EventEmitter = require("events").EventEmitter;
new TlsSocket(new EventEmitter(), { isServer: false });

[Havvy]

I tried using a plain object instead of an EventEmitter and I got a JS error message. I tried removing the isSetter property, but it told me to pass a third argument then.

It has nothing to do with libuv, it is about tls_wrap.

Triage: still an issue with today's tip-of-master.
