Hide category if empty

@thomas.frobieter: Are the classes correct and can we leave the label empty or remove it entirely?
This should only show up as flag, if it is developer content and the user has the permission to view it. So the "No" should never be shown.

Removed the label wrapper. The classes are correct.

We need to align the tests now accordingly!

Tests are green again!
