This commit fixes a test that only fails on certain users machines where Vagrant ends up trying to run real guest capabilities to test if the docker provisioner raises an error if the provisioner install failed. It fixes it by mocking out the expected return values for those capabilities rather than relying on them actually running for this specific unit test.
