🐛 re-run init migrations protection (#7899)

no issue

- if re-running the init scripts (for example: you lost the init rows in the migrations table), then it was throwing errors
- 1. the owner slug and email can change -> no match and it tried to reinsert the user with id 1, which failed
- 2. querying an inactive user is not allowed, because the user model protects against it
