Fix error when viewing merge request with a commit that includes "Closes #<issue id>".

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/488 was giving a 500 error, and the logs showed this was the error.

I'm not yet sure why project would be `nil` in this case, but that's another issue.

Fix reference links in dashboard activity and ATOM feeds.

References like `@user` were not linked on the dashboard activity feed and in Atom feeds, because the reference parser depends on `@project` which isn't set in those situations.

This MR passes the project in question to the reference parsers in an option.
