fix(@embark/cli): start the dashboard after services are started

Start the `embark run` dashboard after services have been started so the REPL
instantiated by the dashboard can successfully request the `console:history`
event.

Delete `cmd/dashboard/command_history.js` since it's no longer in use.

src/cmd/cmd_controller.js
