`UriExt` roundtrip fails for WSL2 Windows

[Sysix]

I could not get test_path_roundtrip_conversion to work on my WSL2 Win10 Machine.

failures:

---- uri_ext::tests::test_path_roundtrip_conversion stdout ----

thread 'uri_ext::tests::test_path_roundtrip_conversion' panicked at src\uri_ext.rs:145:9:

Inside #53 I get another error:

Is this still the case with #53 and #56 merged?
