Forced to return config in the plugins file even I don't change it

[elevatebart]

Current behavior

In component testing, if my plugins/index.js files function does not return config (see below), the command log displays a "no tests found" error see #16812

// faulty cypress/plugins/index.js
module.exports = (on, config) => {
  on('dev-server:start', (options) => {
    return startDevServer({ options, webpackConfig })
  })
}
