Merged PR 5234: Remove 2 fields that no longer exist

# Description

Removes 2 fields that no longer exist in the backend. Needed to do since I need to bring another table to sync_core.

No PBI dependencies found.

Fields are:
* flag_as_problem in SH User
* autonavigate in VerificationSet

# Checklist

- [X] The edited models and dependants run properly with production data.
- [ ] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [ ] I have checked for DRY opportunities with other models and docs.
- [ ] I've picked the right materialization for the affected models.

# Other
