KMS: fixes the kms failing tests.

[white0ut]

Fix the tests introduced in #816.

Some code was still calling encrypt(...) with a key version.

weird, commits from my personal machine weren't picked up by Google CLA. Should be fixed now.

Well, it didn't quite make it. Something I should do?

Following up. It looks like there is no set-primary-version sample, and thus, new key versions aren't being set to primary during tests. This explains why the previous code parsed the active key version then manually called that version on encrypt calls.

Right now it looks like the test project has N key versions, and the primary is set to 1. I'll update these tests so each test does a "rotate", aka a create + set-primary.
