Fix TypeError: t.body is null

[garronej]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch stream-http@3.2.0 for the project I'm working on.

Problem started to arise with empty response body with latest version of Firefox (I think).

Here is the diff that solved my problem:

diff --git a/node_modules/stream-http/lib/response.js b/node_modules/stream-http/lib/response.js
index 91d1900..aeab6b3 100644
