closes#10518
- we had a very generic logic to remove "unwanted" null values
- copied from v0.1
- originally added in 7d4107fec4
- this logic transformed: settings = [{key: 'key', value: null}] to [{key: 'key'}], which is wrong
- i've removed this generic logic completely, because i don't know which purpose it serves
- if there a specific case where we want to remove null values, we should either use the JSON schema or use a specific serializer for the target resource
- added tests to proof that settings API behaves as it should
- one test failed because we removed the isNull logic -> if you send published_at = null on a published post
- the model layer has a piece of logic to force a date if you set published_at to null if the status is published
