Travis tests failing

[Hosweay]

So recently the Travis tests have been failing. The tests use the latest Vault Docker image and with the release of 0.10.0 they introduced versioned secrets. The tests are assuming the old unversioned option of secrets but the secret path of the new image is defaulting to v2.

I will submit a PR shortly that will setup the Vault used by Travis tests to use v1 again. This should make the tests pass again.
