Fix emoji transform to Matrix

Fix emoji transform to Matrix

Fix #2641 (closed)

Follow-up from !2077 (merged) which throws an error when we try to deploy in production because emojify is not available.

We ignore the public/repo/ directory in our build-scripts which holds emojify so it's not available on disk. For the frontend, it's already bundled in by webpack.
