test/e2e/upstream-proxy.feature is flaky

[johnjbarton]

Seems to fail more than pass.

The failure call stack points to https://github.com/nodejs/node/blob/master/lib/_http_client.js#L435
indicating that socket was closed before a response was sent but without an error on the request.

The fail can be reproduced on some runs with just the single cucumber test running:
https://travis-ci.org/github/karma-runner/karma/jobs/673177446

Looks like the test is complete, the socket is still polling then the fail:
