Support for TestRPC.provider()

[IstoraMandiri]

I'd like to run my tests using an eth-lightwallet keystore and hooked-web3-provider.

This is working great with TestRPC if the transactions are sent over HTTP, but using TestRPC.provider() fails if I try to implement HookedWeb3provider (which seems to assume a HTTP host).

I was hoping to do something generic like this, that supports both HTTP hosts and TestRPC.provider()

  // create the provider for web3 transactions using ks
  const hookedProvider = new HookedWeb3Provider({
    ...web3.currentProvider,
    transaction_signer: keystore,
  });
  // update the web3 instance to use our new provider
  web3.setProvider(hookedProvider);

However, it fails with:

Error: Invalid JSON RPC response: Error: connect ECONNREFUSED 127.0.0.1:8545

Happy to help with a PR this is within the scope of hooked-web3-provider. Is it?

This project was basically abandoned in favor of provider-engine, which can be used to easily configure something like hooked-web3-provider, or something more advanced!
