using rpc in contracts.js w/ blockchain proxy = true throws error

Bug Report

Summary

Things seem to work, but an error is emitted during deployment.

Current behavior

How to reproduce

run embark console with the following config:

contracts.js:

deployment: {
      host: 'localhost', // Host of the blockchain node
      port: 8545, // Port of the blockchain node
      type: 'rpc',
}

blockchains.js:

development: {
    proxy: true
}

Expected behavior

may not be a big deal b/c rpc is deprecated, but still confusing to the user.

If you encounter an error, please create a logfile using the following command and post the output here

$ embark run --nodashboard --logfile log.txt --loglevel trace
