responses 0.15.0 not setting cookies

Environment

responses 0.15.0

Steps to Reproduce

from unittest import TestCase

from requests import Session
from requests.adapters import HTTPAdapter
import responses
from urllib3.util.retry import Retry


class TestSession(TestCase):

  @responses.activate
  def test_cookies_enabled_on_session(self):
    responses.add(responses.GET, "http://test.com", body="resp", status=200, headers={"set-cookie": "foo=bar"})
    sess = Session()
    retries = 1
    retry = Retry(
        total=retries,
        read=retries,
        connect=retries,
        status=retries,
        backoff_factor=0.1,
        status_forcelist=frozenset([500, 502, 504]),
    )
    adapter = HTTPAdapter(max_retries=retry)
    sess.mount("http://", adapter)
    sess.mount("https://", adapter)
    resp = sess.get("http://test.com")
    assert resp.text == "resp" # True
    assert sess.cookies.get("foo") == "bar" # False, should be True

Run above with pytest.

Expected Result

With 0.14.0, the above test passes, which is the expected result (cookies should be set).

Actual Result

In 0.15.0, the above test fails as the cookie are not set.

@chadwhitacre fixed on latest master and should be in 16.0
