This commit adds the utility testing function TempDir, which provides a tester with a temporary directory as well as a means of cleaning up that directory. The new function is implemented everywhere that makes sense throughout the code base. This also cleans up the directories left behind by go-git's testing fixtures. Some light refactoring was also performed in this change. Change-Id: I754484934660487140f57671bacb5463cf669e3e
