The LastCommitCache code is a little complex and there is unnecessary duplication between the gogit and nogogit variants. This PR adds the LastCommitCache as a field to the git.Repository and pre-creates it in the ReferencesGit helpers etc. There has been some simplification and unification of the variant code.
