On resetting packages to default in templates, Scriptable Render Pipeline loses Render Pipeline asset reference in Settings under Graphics. Hence a black screen is rendered in Game view and in Scene view the gameObjects don't render. This happens in all templates except 3d with extras.

Steps to reproduce:
1) Create a new project with template HDRP/ LWRP/ LWRP with VR
2) Help > Reset packages to default.

Actual result: Game view renders a black screen and in Scene view the gameObjects don't render.

Expected result : Packages get reset on clicking resetting packages to default.
