Connection reset by peer error on URL's with parameters

[viccherubini]

When using HTTPretty with URL with parameters, the connection will eventually die and return with an error that says:

ConnectionError: [Errno 54] Connection reset by peer

Note: this is when using the Requests library. However, if the URL does not have any parameters, then HTTPretty works fine.

# Fails
HTTPretty.register_uri(HTTPretty.GET, 'http://example.com/index.php?id=10', body='example response', status=200)
r = requests.get('http://example.com/index.php?id=10')

# Works
HTTPretty.register_uri(HTTPretty.GET, 'http://example.com/index.php', body='example response', status=200)
r = requests.get('http://example.com/index.php')

I wish I knew enough Python to offer a pull request. Anyway, it's a great library, but this one bug is preventing me from using it. Thank you!
