readyStateChange is not called when useFilters is true.

fake_xml_http_request.js

        open: function open(method, url, async, username, password) {
            ...

            if(sinon.FakeXMLHttpRequest.useFilters === true) {
                var xhrArgs = arguments;
                var defake = some(FakeXMLHttpRequest.filters,function(filter) {
                    return filter.apply(this,xhrArgs)
                });
                if (defake) { sinon.FakeXMLHttpRequest.defake(this,arguments); }
            } else {
                this.readyStateChange(FakeXMLHttpRequest.OPENED);
            }
        },

I think "this.readyStateChange" should be called when "useFilters" is true and "defake" is false.

I'll have a look at this. From a first look I think you're quite right - if we're using filters, but not de-faking, we should be in the default branch,

Github marks the issue as closed on Tim's pull request, I merged it, yet... It's still open :|
