Fix broken auto_tagger example

[johnhampton]

In auto_tagger.rake stage.revision returns both the sha and the named
ref. This causes git update-ref to fail. Passing only the sha portion of
stage.revision to create_and_push resolves the issue.

Here is the error that I received:

cd "/Users/john/Projects/tan-expedite" && git fetch origin refs/tags/*:refs/tags/*

Pulling in @kmayer as he wrote more of this code.

Instead of this fix, should stage.revision just return the SHA from git_revision instead of passing that to git_named_rev?

I'm on vacation this week, so it might be a week before I can look into it. Not a clue. If the method name doesn't provide enuf guidance, then it might be worth a look.
