Fix for fatal: not a git repository: '.git'
    Removed all os.chdir() statements

See: https://github.com/DonJayamanne/gitHistoryVSCode/issues/233#issuecomment-375769718
    Just before calling any hooks, git sets several env vars, among them is one called GIT_DIR
    which points to the git index dir (if you're at the top level, it will be set to .git prior to calling your hooks)
    The GIT_DIR setting becomes invalid when the hook does a chdir and calls git reentrantly to figure out the git top level dir.
