Fix CPU compositor crashes when rendering older files

Browse Source 
How to reproduce:
1. Save blend file in 4.2 with preview active for composite or viewer node (see attached example file)
2. Load blend file and render
3. Observe crash

Preview for composite and viewer node was removed in https://projects.blender.org/blender/blender/pulls/127044, but versioning was not addressed in that PR.
