Shader Graph Templates window icons are replaced with Custom VFX Graph icons after viewing VFX Graph Templates

Steps to reproduce:
1. Create new Unity project
2. Make sure VFX package is installed
3. Open Shader Graph Templates window
4. Observe the icons in the categories
5. Open VFX Graph Templates window
6. Reopen Shader Graph Templates window
7. Observe the icons in the categories

Actual results: Shader Graph Templates window uses Custom VFX Graph icons instead of Shader Graph icons after reopening the Templates window

Expected results: Shader Graph Templates window uses the same Shader Graph icons after reopening the Templates window
