test-tcp fails on WSL ubuntu 18.04.

[SinisterRectus]

This test is new with the upgrade to libuv 1.32.0.

Uncaught Error: tests/test-tcp.lua:158: assertion failed!

In the read_start callback, data and err are both nil.

Encountered on WSL ubuntu 18.04. Cannot reproduce on native ubuntu 16.04 on a different machine. Not tested on native Windows 10 on the same machine.

Maybe it needs to match this assert?

For reference, the Libuv test never checks for ECONNRESET: https://github.com/libuv/libuv/blob/v1.x/test/test-tcp-close-reset.c

This is not an issue in WSL2. No idea what causes it in WSL1. Probably not worth investigating.
