TokenReg clojure support improvements

* allow loading of parity tokenreg contract data from any address,
  including our own test instance
* use tokenreg data from config.edn for testnet only when availaned,
  otherwise from our smart contract on rinkeby
* clean up + refactoring
* remove generated java wrapper for parity tokenreg contract
