- The corrupted data recovery mechanism for notifications is needed to be able to fix the data stored in `settings` table under `notifications` key. There was no validation in place, which has caused some instances to store data in unreadable/writable state
- The recovery mechanism is in place to avoid adding migrations every time we spot a broken notifications data (will be fixed by validation soon).
- The notification data is also NOT critical but valuable for system functioning properly, that's the reason why the data "healing" happens in less secure "fire-and-forget" way
- The referenced commit is where the "bigger" problem that was causing the data corruption was at. This change is a "cleanup" after what has happened there - storing Ghost error object in `value` for `notifications` key

- Fixed failing test cases which were designed to check non-major upgrade messages. There's no clear use cases for those, but still worth keeping such case in mind

- The notification to upgrade to new 4.0 Ghost version was still visible to users after upgrading the instance to 4.0. This was caused by notification filtering not taking into account 3.x or 4.x versions.
- The fix filters out notifications that detect a major version notification using `x.0 is now available` pattern and compares current version to that major. This should future proof the issue from happening in Ghost 5.0 (but a proper holistic fix is preferable!)
