Fixed parameter reading on Windows.

(We are parsing a URL, and even though it represents a file, it's still
a URL, so it uses the standard slash and not the microsoft slash.)
This will make SDK testing work on Windows.
We suck a lot for not fixing this sooner, but
- I didn't have Windows set up for development.
- It was broken for so long, we deprioritized and then sorta forgot about it.
This has been broken for over 5 months, when I last touched this file
to make it work on Macs.
