fix: format errors properly (#194)

* Format errors properly with wp

I just faced the issue with superstruct errors in webpack-nano.
Error message is not shown. In this diff I created new instance
with builtin error constructor.

```
⬢ wps: An option was passed to WebpackPluginServe that is not valid
Error:
