github pages deployer does not return to current branch

[mojavelinux]

The github pages deployer does not return to the current branch correctly. Instead, it always returns to master (which, by chance, may correspond to the current branch).

In the file lib/awestruct/deploy/github_pages_deploy.rb, the current branch is captured using:

current_branch = git.branch

However, the branch() method does a checkout on the specified branch, defaulting to master. The correct function for capturing the current branch is current_branch(). Thus, the line above should be:

current_branch = git.current_branch

See https://github.com/schacon/ruby-git/blob/master/lib/git/base.rb for details.

I think a fix should be accompanied by a test as it's a very testable assertion.

FWIW, I think our strategy should be to always include a test for every issue. It's the best (maybe only) way to start getting some code coverage.
