fix: do not print event diff when the ids have changed

[leonmk-aws]

Fixes #2248

Description of the bug

When checking for the database diff, the eventRootProperty and eventResourcesField of events were shown as changing like:

│          ├[~]  event aws.autoscaling@EC2InstanceLaunchLifecycleAction
│          │  └      - rootProperty: EC2InstanceLaunchLifecycleAction
│          │         + rootProperty: EC2InstanceLaunchLifecycleAction
│          │         - resourcesField: [EC2InstanceLaunchLifecycleAction.AutoScalingGroupName]
│          │         + resourcesField: [EC2InstanceLaunchLifecycleAction.AutoScalingGroupName]

This was caused because they used JsonEq for comparison, which also checked if they has the same $id in the db, which is not always true (e.g. when adding a new resource to the db, ids will change).

Solution

Do not compare the ids, but use the existing functions to compare the EvenTypeDefinition in these properties.

Testing

• Ran the diff script on databases where the ids had changed, diff is now correct.
• Added a unit test
