app.clearRecentDocuments does not clear files from the recent entries list

Issue Type: <b>Bug</b> Even if I clear recently opened files they still show up in the (live) Tile in the Windows Start menu. I don't want them to show up, especially because this is a very long list. It takes 3/4 of the screen. Steps to reproduce: 1. open some files in different locations 2. clear opened recently 3. close vscode 4. right vscode click tile in the start menu 5. there's still a list (it will be there even after restarting PC). VS Code version: Code 1.46.1 (cd9ea6488829f560dc949a8b2fb789f3cdc05f5d, 2020-06-17T21:13:20.174Z) OS version: Windows_NT x64 10.0.19041 <!-- generated by issue reporter -->
