build: fix running e2e locally with staging build env (#302)

# Motivation

Fix e2e error `[WebServer] Error: Not found:
/components/workers/analytics.worker.js` by introducing a staging mode
that can be use to build and run the test in order to avoid loading the
analytics.

# Changes

- add mode `stagin`
- build test with staging instead of build
- don't load anyltics on staging
