Publish stories about objects in projects as related to projects
Summary:
Fixes T5456. We lost this logic in the transition to applicationtransactions.
When publishing a feed story, mark all of the object's projects as related, so the project filter in feed works.
Test Plan: Made a comment on a task associated with a project, saw the story in filtered feed.
