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.

Addresses #2268.

See merge request !1793

Fix mentioning of private groups.

`issue.participants` would mistakenly not send the `current_user` to `mentioned_users`, which means it would search for referenced groups and users as if the user was signed out. Since signed out users don't have access to private groups (groups without public projects) and since you can't reference a group you don't have access to (since this would leak its existence), the group reference wasn't found and the group members weren't notified.

Addresses internal issue https://dev.gitlab.org/gitlab/gitlabhq/issues/2326.
