Load Image node error

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

This started with latest two versions of ComfyUI.

When I start ComfyUI Load image node in the workflow shows with red outline and error pops up:

```
Some nodes are missing required inputs
```

When I cllick to see in error panel it is showing the Load Image node which as you know has no inputs.

The workflow executes, so it's probably just a wrong check.

Note that if there are multiple Load Image nodes they all get red outline.

### Steps to Reproduce

1. Make a workflow with Load Image node.
2. Save it.
3. Close ComfyUI
4. Restart server.
5. Open ComfyUI
