Subject: [PATCH] Fix React.act infrastructure issue in jsdom component tests
 (#320)

The host environment has NODE_ENV=production, which causes React's CJS
entry point (react-dom/test-utils.js) to load the production bundle
where React.act is not exported. Add an explicit define to override
process.env.NODE_ENV to 'test' in the component test config so the
development bundle is loaded instead.

Fixes #320
