Multiroot workspace wrong label

[rebornix]

Issue Type: Bug

Create a multiple root workspace with following settings

"folders": [
                {
                        "path": "vscode"
                },
                {
                        "path": "vscode/extensions/notebook-test",
                        "name": "notebook kernel test"
                },
                {
                        "path": "prototype/notebook-test"
                }
        ]

The repository picker will then show two items

- notebook kernel test
- prototype/notebook-test

After choosing the first one, I find it's actually just vscode repo instead of vscode/extensions/notebook-test so only the label is wrong.
