Don't put the entire corpus into project edit feed stories

Summary: Fixes T8723. We override timeline titles for these fields to shorten them, but the parent class shows full values for feed edits, which can lead to screen-sized notifications.

Test Plan: Edited a project, saw a reasonably-sized notification for it.
