WorkspaceEdit.createFile leads to undefined error

[pelikhan]

Type: Bug

Undefined access when previewing a createfile edit.

• Run this code in a workspace command:

const edit = new vscode.WorkspaceEdit()
// unique new file name
const fn = vscode.Uri.joinPath(vscode.workspace.workspaceFolders![0].uri, Math.random() + ".txt")
const contents = new TextEncoder().encode("hello world")
// create new file edit
edit.createFile(fn, { overwrite: true, ignoreIfExists: false, contents }, { label: "hello world", needsConfirmation: true })
// opens refactoring UI
vscode.workspace.applyEdit(edit, { isRefactoring: true })

• Click on file preview in refactoring UI
• You will get an "undefined ... when trying to read 'template'"
