BS Lighting Shader Object Type information gets lost at export

Issue Overview

Exporting an object for Skyrim SE as nif with material settings
Shader Type: BS Lighting Shader Property
BS Lighting Shader Object Type: ENVIRONMENT_MAP
does not work.

When checking the exported .nif inside Nifskope the shader type is set to "Default"

This will cause the CreationKit to crash with a fatal error when using the related shader flag "Environment_Mapping"

For me it crashes Skyrim itself (LE). The problematic line is here: https://github.com/niftools/blender_niftools_addon/blob/master/io_scene_niftools/modules/nif_export/property/shader/__init__.py#L97

bsshader.skyrim_shader_type should be changed to just bsshader.shader_type.
