FBodyInstance SetCollisionEnabled not properly checking physics state.

FBodyInstance::SetCollisionEnabled uses an incomplete conditional to determine whether or not it's in a Simulating or Non-Simulating state. This can cause cases where RecreatePhysicsState doesn't properly get called on PrimitiveComponents.

In most cases, this isn't a seen issue because EnsurePhysicsStateCreated may cover it up.

1. Create a child of UPrimitiveComponent in C++.
2. Override the OnCreatePhysicsState method and print that it's been called (see attached file).
3. Override the OnDestroyPhysicsState method and print that it's been called (see attached file).
4. In BeginPlay for this component, toggle between all physics states (see attached).
5. Add this component to an actor in the level.
6. PIE

Expected: "OnCreatePhysicsState - Called" should be printed for each transition from a non-simulated state (NoCollision or QueryOnly) to a simulated state (PhysicsOnly or QueryAndPhysics) and "OnDestroyPhysicsState - Called" should be printed for each transition from a simulated state to a non-simulated state.

Actual: Several transitions from simulated states to non-simulated states (and vice versa) do not trigger the expected calls.
