Unable to clone custom nodes repo

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Should be able to install any custom node via manager. If it wasn't able to, it should not act like it did successfully and prompt the user to "restart"

### Actual Behavior

Installation Error, and prompts the user to restart to use the custom node.

### Steps to Reproduce

Try installing many custom nodes through the legacy manager.
