If you use .insert on Write<StorageCollider> you might cause a unwrap() to fail

1. Create a collider and do a tick
2. Replace that with a new collider using Write::insert
-- Modify event is created by Specs, not Remove and insert --
3. let collider_handle = physics_collider.handle.unwrap(); - This line in sync_colliders_to_physics (update_collider) will panic

--

Workaround,
Use Write::remove first.
