Disabling DynamicNavigationMeshSystem causes the error: System.NullReferenceException: 'Object reference not set to an instance of an object.'
Dynamic navigation doesn't work if DynamicNavigationMeshSystem is registered before NavigationProcessor

To Reproduce
Steps to reproduce the behavior:
For bug 1:

Get DynamicNavigationMeshSystem and Enable = true
Get DynamicNavigationMeshSystem and Enable = false
Game throws the error

For bug 2:

Load the game without any navigation components and manually add DynamicNavigationMeshSystem to IGameSystemCollection
Load/add scene with navigation components.
NavigationComponent.TryFindPath always fails because the nav mesh is never set.
