dispose subscription handler on HttpServer disposing

[almostWaldo]

Problem: a subscrition handler is not disposed on HttpServer object destroying. As result it leads to hang threads and process. Looks like it's work-related Rx Observable collections. This problem was found with test:

[Test]
public void TestDisposing()
{
    for (var i = 0; i< 10000; i++)
        using (var server = new HttpServer("http://*:1234/"))
        {
        }
}

This test hangs before the fix and works fine after
