fix #101 : fixed compare URL with query string

[smilexx]

Hi. Added the ability to make a request with query parameters. Please see the request.
#101

Example:

mock.get('http://example.com/api/user', (req, res) => { return res.status(200).body('{"data": "1"}'); });

xhr.open('http://example.com/api/user?test=1');

Thanks for your contribution!

Could you please add a test that would be failing without this fix.

How do you think we version this? Given the behaviour has been in the wild for a while, do you think this will break users who have come to expect the broken behaviour?

Perhaps a better fix could be #101 (comment) ?
