[Windows] Fix TestURL/test_URLStrings

Since '|' is a valid character in a url on Windows as implemented by
CoreFoundation, on Windows, we should expect that `unescaped|pipe`
should be properly parsed.

This is hacky, but adds a test case on Windows, and disables it on other
platforms and vice versa.
