[CI] AppVeyor build fails inexplicably

[vexx32]

:ghost: Brief Description

AppVeyor builds are failing completely due to a missing path.

Version

Current latest commit.

Environment

Looks like we're running against a Win2012R2 client in AppVeyor, not sure what OS is actually running the task though.

Steps to Reproduce

AppVeyor runner invoking the standard test run.

Expected Result

Tests pass, or at least we get an indication of specific failing tests if there are actually any.

Actual Result

Test Kitchen fails with a missing directory error:
