Webpack 5 test repo

Reproduction repo for issue in webpack 5

When using MultiCompiler, webpack node-api and compiler hook that gets stats from compilation (like webpack-dev-middleware do) - file rename leads to Error TypeError: Cannot read property 'getTypes' of undefined

How to reproduce

1. Clone this repo

2. Run cd webpack5 && npm ci && npm start

3. Rename file inner.js (e.g. inner.jsx, other.js)

   You should get error

   TypeError: Cannot read property 'getTypes' of undefined
