RectAreaLightNode: Fix update().

[Mugen87]

Related issue: -

Description

The PR fixes a bug in RectAreaLightNode that appears when you produce a frame with more than one render() call and different cameras. My use case was updating a CubeCamera per frame and using its cube render target as a texture for objects.

The default update type of analytical light nodes in FRAME. This is fine for most modules but RectAreaLightNode depends on the view matrix in its update() method. If there is only a single update per frame, RectAreaLightNode uses wrong uniform values when rendering the scene with subsequent cameras.
