When the feed query on project profile pages overheats, contain the damage
Ref T13349. This is almost the same change as D20678, but for project profiles instead of user profiles.
The general reproduction case is "view a project where you can't see more than 50 of the 500 most recent feed stories".
- Forced all queries to overheat.
- Viewed a project profile page.
- Before: overheating fatal near top level.
- After: damage contained to feed panel.
