Undo changes for travis-tested tagging.
Undo changes for travis-tested tagging.

We've decided against using a travis-tested tag for public repos. There are a
couple of reasons for this undo. We currently don't have a way to push tags to
github through a public repo through travis and we also want to preserve
semantic versioning for public facing apps.
