Execute cells FAILED on Kubernetes pod

Issue Type: Bug

When running a cell in an existing notebook (i.e. one that is saved somewhere) on a Kubernetes pod, the cell does not execute. The following is logged to Remote Extension Host:

[2021-06-29 04:51:14.316] [exthost] [error] NotebookController[1] execute cells FAILED {}

Furthermore, the output in developer tools shows:

Error: duplicate execution for vscode-notebook-cell://k8s-container...

I can provide the full output if that would be helpful.

Note: In a fresh, unsaved notebook created using Jupyter: Create new blank notebook, the cells execute without problem. The problem only manifests once the notebook is saved.

Steps to reproduce:

1. Open VSCode on a Kubernetes pod
2. Create a blank notebook
3. Save the notebook to disk somewhere
4. Attempt to run the first cell

There’s another issue with that sort of URI https://github.com/microsoft/vscode-remote-release/issues/5250. It’s possible that the weird URI format could cause an issue like this too. Sounds like it will be fixed in the Containers extension

[IanMatthewHuff]

Looks like this has been fixed with the most recent VS Code + Containers Extension release. Please ping here if you are still seeing it with everything updated.
