Issue description

Adding a new ConvexCollisionShape3D resource to a CollisionShape3D node throws the error:

E 0:00:09:624   _setup: Failed to build convex hull
  <C++ Source>  modules/godot_physics_3d/godot_shape_3d.cpp:1100 @ _setup()

The same error happens when creating a new ConvexCollisionShape3D object via script.

I think the issue was introduced when the CollisionShape3D custom debug color and fill was added.

As far as I can tell, it does not produce any problem at runtime. The collision shape works as expected.

Steps to reproduce

• Create a CollisionShape3D node
• Add a ConvexCollisionShape3D to its shape
• Check the output

I'll bisect this one.

Indeed a regression from custom debug shape color (pr #90644), CC @BattyBovine
