Summary:
Fixes T8209. Using handles can now cause cache fills as a side effect of T7707. Use a raw query instead.
I'll follow up on T8209 with some context and ideas for longer-term fixes.
Test Plan:
- Set event names to `''`.
- Reran migration with `--apply ... --trace`.
- Saw migration work correctly without executing cache fills.
