Fix reloading of lotus console

I was playing with console reloading and I see this on current master:

```
$ lotus console
2.1.2 :001 > reload!
Reloading...
Commands:
  lotus console         # starts a lotus console
  lotus help [COMMAND]  # Describe available commands or one specific command
  lotus server          # starts a lotus server
$
```

So here goes the fix that adds ```console``` argument to the execution path.
