Description

Steps to reproduce

• Create a private repository
• Star this repository
• Log out or open a private tab
• Open the user's profile page with the stars tab (e.g. https://gitea.tld/user?tab=stars)

---

If a user stars a private repository, it still shows up as a little one in the starred page overview.
This doesn't expose too much private information, but it's confusing to see that one project is starred whilst seeing an empty list in the overview.
