Update overriding code of twitter/connection.rb

http gem 0.9.8 does not provide port number when uri_object.port is called.

Addressable::URI may be the source of this problem, however calling uri_object.default_port seems reasonable when an authority is given properly, in other words, given port and default port is same.

I monkeypatch this problem until proper fix is applied.
