Godot: OBJ files can't be imported as a scene

[fracteed]

Operating system or device, Godot version, GPU Model and driver (if graphics related):
Win10 and Linux Mint

Issue description:
When using the menu option Scene>open scene , it is no longer possible to open an OBJ file. The scene does open, but the mesh instance nodes are empty and do not reference any mesh files.
This function broke when the "OBJ as mesh" option was made as the default in the importer. Even when changing the importer option to "import as scene" and reimporting, it makes no difference.

Importing a scene still works correctly for dae and gltf files.

Steps to reproduce:

• Use Scene>open scene and try to open an obj file

Isn't it a choice in the import dock?
