Merge #1650: Remove convert_old_wallet.py script

d89dcde Remove convert_old_wallet.py script (Kristaps Kaupe)

Pull request description:

  Old wallet format isn't used for years and script is broken since removal of pyaes dependency in #1526. If somebody still needs it, he can use older JoinMarket version to do conversion.
