Webpack plugin not applied

[JMPSequeira]

What is the current behaviour? Webpack Plugin never applied

Steps to reproduce the behavior:

1. add a webpack plugin in preact.config.js

   
   import WriteFilePlugin from "write-file-webpack-plugin";
   import path from "path";

export default (config, env, _) => { config.output = config.output || {}; config.output.path = path.join(__dirname, "./wDist"); config.plugins.push(return new WriteFilePlugin()); };

2. run preact watch -c ./preact.config.js
3. Plugin apply never called

**What is the expected behaviour?**
Expect plugin to be applied
