Revert emergency fix

This reverts the emergency fix put in by #3699.

We do not want disappearing content under any circumstances.
After investigating (and trying to recreate) the issues that happened last week around the Content API, I have come to the conclusion that the Content API was giving back empty `results` and `editorsPicks`.

We are currently deciding what to do when this does happen, and under what conditions to fail.
