Test failures on node v14-v16

[joeyparrish]

I get the following test failure on Linux after fixing the macOS failures in #393 with PR #394

  1) socket cleanup
       should cleanup sockets on ERR_STREAM_PREMATURE_CLOSE (using stream.pipeline):

      Uncaught AssertionError: expected 1 to equal 0
      + expected - actual

      -1
      +0
      
      at Assertion.fail (node_modules/should/cjs/should.js:275:17)

Reverting the fix in PR #392 does not fix this test failure. Same for the fix in PR #394.

I can't tell from the git commit history why this was commented out, but uncommenting this line in the test fixes it:

    stream.pipeline(resp, writable, function(err) {
      err.code.should.eql('ERR_STREAM_PREMATURE_CLOSE')
      // if (err) resp.request.destroy();
    });

@tomas, any insight on that? I'll put up a PR in case that's the right fix. If it's not... I'll need you to figure it out. I'm out of ideas.

I should have mentioned, this failure was on node v16. When I run tests on macOS with node v16 or v14, I get this failure, too. So it's not specific to Linux after all.
