Physics Interpolation 2D - fix light and light occluder resetting

Browse Source 
It turns out `NOTIFICATION_TRANSFORM_CHANGED` is deferred for these nodes, which can mean the transform is not set in the `VisualServer` until after the reset has been sent, even if the transform is set before the reset in script. This prevented the reset from acting correctly.

Here we explicitly set the transform prior to each reset, to ensure the `VisualServer` is up to date.
