Crash when removing a RigidBody Object using notifyOnContact

[moisesjpelaez]

Description
When a RigidBody is removed inside notifyOnContact the game crashes. This happens because the PhysicsWorld still runs lateUpdate. Adding an if (rb != null) inside the for loop here fixes the issue, but I don't know if that's the proper solution.

To Reproduce

1. Add a Haxe trait to a RigidBody
2. Add object.remove() inside the RigidBody.notifyOnContact notifier

Expected behavior
To remove an object containing a RigidBody from notifyOnContact without errors.

System
Blender: 3.6.11
Armory: 2024.07
OS: Windows 11 Pro (x64)
Graphics card: NVIDIA GeForce RTX 3050 Ti Laptop

I remember something similar with the contact array node in a project. I just threw a try catch to prevent the crash directly in the node if you think a try catch is a better solution
