* Use different messages for UTDs sent before login * Playwright test for historical events * Add some tests * initial work on pre-join UTDs * add playwright tests and remove old pre-join UTD logic * run i18n script * fix type error * use different error code in PostHog for pre-join UTD * don't remove old pre-join UTD logic yet --------- Co-authored-by: Richard van der Hoff <richard@matrix.org>
