- Additional validation protects from problems like the ones in refed commit from even getting through to the database.
- At the moment only used notificatons and couple more settings to ensure they are arrays when passed into the API. This is to avoid making big change in settings straight away - this is a problematic area which needs cautious approach.
- Ideally in the future the list of settings to check the "array" type (and other types) should be automatically generated based on the default-settings.json (or whatever way we define settings in the db a that moment)
- There's an ugly code-tripplication going on in this change. This is a separate topic that will be addressed once we work on API cleanup.
