What happened?

When using the --addr flag with empirica serve, the parameter is ignored and the server starts on port 3000 anyway.

Steps To Reproduce

1. Create a new project
2. Bundle the project with empirica bundle
3. Try to serve to any port other than 3000, eg by running empirica serve --addr ":3005" bundlename.tar.zst
4. The app will still be served at localhost:3000
