Lifecycle broken for persons on events
Bug description
With persons on events, the lifecycle query says there are no new users until the week of 20th June, when there are many

How to reproduce
- Create lifecycle insight far enough back
Environment
- [ ] PostHog Cloud
- [ ] self-hosted PostHog, version/commit: please provide
Additional context
Thank you for your bug report – we love squashing them!
A whole bunch of persons didn’t get their person_created_at column properly migrated so it’s defaulting to a 1970 creation date which is skewing the lifecycle query results since it's attempting to use the new column
@neilkakkar Think we should flag lifecycle separately for this reason?
Damn. Yeah, makes sense.
Do you know if the same happens on self-hosted?
