Space-IDs are shown instead of name in activities

[Svanvith]

When you look in the activities from a file or folder, the space-id is shown, instead of the name

It is on Version 3.7.0 and 4.0.0-rc.1

I looked into it with @AlexAndBear and we saw, that the backend is sending not the name of the space.

It only happens with already created users, with new created users the Space name is shown.
