🐛 [Bug] Backend - Pinned post of secret groups are also visible for users that are not member

🐛 Bugreport

As member or admin of a (secret, privat or public) group I want to be able to pin a post. The actual function makes the post pinned on the overview and visible for every network user. The optimal solution would be that as member of a secret or privat group I see the pinned posts in the overview and in the group as first posts!

• Remove in the getPosts query the pinned posts of privat and secret groups that I am not member
