assert_call_count should be able to check urls without matching querystring

[pmourlanne]

When adding an url in responses, querystring is not matched by default:

@responses.activate
def test_my_test():
    responses.add(responses.GET, "http://www.example.com")
    # Both these requests will be captured
    requests.get("http://www.example.com")
    requests.get("http://www.example.com?hello=world")

assert_call_count doesn't reproduce this behaviour:

@responses.activate
def test_assert_call_count_always_match_qs():
    responses.add(responses.GET, "http://www.example.com")
    requests.get("http://www.example.com")
    requests.get("http://www.example.com?hello=world")

    # One call on each url, querystring is matched by default
    responses.assert_call_count("http://www.example.com", 1) is True
    responses.assert_call_count("http://www.example.com?hello=world", 1) is True

I would like to be able to check the call count on one particular url without matching querystring, eg.:

@responses.activate
def test_assert_call_count_match_querystring():
    responses.add(responses.GET, "http://www.example.com")
    requests.get("http://www.example.com")
    requests.get("http://www.example.com?hello=world")

    responses.assert_call_count("http://www.example.com", 2, match_querystring=False) is True
    responses.assert_call_count("http://www.example.com?hello=world", 2, match_querystring=False) is True
