emissive_color - sequences of dimension 0 should contain 4 items, not 5

See original GitHub issue

Describe the bug

Blender crashes on file

To Reproduce Steps to reproduce the behavior:

Open glb file
See error

Expected behavior Load the glb correctly.

.blend file/ .gltf

Version

OS: linux
Blender Version 2.81 and https://github.com/KhronosGroup/glTF-Blender-IO/pull/857

Additional context

https://github.com/KhronosGroup/glTF-Blender-IO/blob/2ad329e0fdf89803c09df686ca866ee6782542d0/addons/io_scene_gltf2/blender/imp/gltf2_blender_map_emissive.py#L80-L84

Should be:

        else:
            emissive_color = pymaterial.emissive_factor
            if len(emissive_color) == 3:
                emissive_color.append(1.0) # add alpha
            emit.inputs[0].default_value = emissive_color
