Merge #2722

2722: Fix ra_cargo_watch test on windows. r=matklad a=kiljacken

Due to difference in path parsing on platforms, the current input to the snapshot tests in ra_cargo_watch cause a panic when running on Windows. This PR disables the tests when running on Windows until a better solution is found.

If somebody running on Windows could test this that would be great, as I'm working in the blind here :) 

Fixes #2720 (probably).
