Fixes: https://github.com/element-hq/synapse/security/advisories/GHSA-27p5-4f45-gx76
Fixes: https://github.com/matrix-org/internal-config/issues/1717

I've tried my best to make the tests a good narrative for the thought process here,
but essentially the rationale is to make `/get_missing_events` not distinguish
between 'event is in wrong room' and 'event is unknown to me'.
