Handle default ports in WSGITransport (#1469)
* Maybe port is `None`

https://www.python.org/dev/peps/pep-3333/#environ-variables

> SERVER_NAME, SERVER_PORT
> When HTTP_HOST is not set, these variables can be combined to determine a default. See the URL Reconstruction section below for more detail. SERVER_NAME and SERVER_PORT are required strings and must never be empty.

* Add unit test

* Compute default port
