Windows ci breakage

Fixes functional and unit tests on windows. Confirmed fixed in Ci, but Ci has a configuration issue that's failing the build:

```
Finished in 436.14 seconds
6147 examples, 0 failures, 32 pending
Recording test results
Test reports were found but none of them are new. Did tests run? 
For example, C:\Jenkins\workspace\chef-ruby1.9.2-windows\chef\test.xml is 2 days 23 hr old
```

The above should now be fixed.
