Unavailable `bpy.context.screen` while rendering animation prevents updates

Created by: gabrielmontagne

Problem statement

Check for null bpy.context.screen property is_animation_playing in handlers.py sv_update_handler causes nodes to not update when rendering an animation.

Traceback (most recent call last):
  File "/home/gabriel/.config/blender/3.2/scripts/addons/sverchok/core/handlers.py", line 101, in sv_update_handler
    is_playing = bpy.context.screen.is_animation_playing
AttributeError: 'NoneType' object has no attribute 'is_animation_playing'

A workaround I'm using ATM is to assume (most likely incorrectly) that if bpy.context.screen is None, is_playing would be True.

Steps to reproduce

It most likely happens with any Sverchok animation, but I'm uploading my .blend for reference. https://drive.google.com/file/d/1SMOas4Kg3q6SK8W9P6KIFaXxfYMk8zwJ/view?usp=sharing

Open the attached blend file.
Go to Render menu -> Render Animation

Expected result

Grease Pencil object and generated geometry should match on every frame.

Actual result

Generated geometry is not update between frames, so gets out of sync with reference GP object. The above error is displayed on the console.
