This solves [ENG-812: Improve perf of website load](https://linear.app/comm/issue/ENG-812/improve-perf-of-website-load). By limiting the amount of messages that MySQL has to look at in order to resolve `fetchMessageInfos`, we speed up website load significantly.
On my local environment using the prod database, the query resolves in 0.5s instead of 20s.
