Settings Defaults gets very confused when updating extensions.

[Jason3S]

Type: Bug

If the settings schema has changed for an extension during an update, it is not getting correctly detected by VS Code Settings.

Steps to Reproduce

1. Install the Code Spell Checker extension version v3.0.1 (the old version).
   
2. Restart VS Code -- this is necessary if already had the extension installed.
3. Go to the extension's settings.
   
4. Notice the list of settings (59) -- Keep settings editor open.
   
5. Update the extension to v4.0.21.
   
6. Restart extensions as instructed.
7. Notice the list of settings (59) -- which is incorrect.
   
8. Closing the settings editor and reopening doesn't make a difference. It is still showing stale settings.
9. Even Restarting the Extension Host does not work.
10. The only option is to Restart VS Code.
11. Restart VS Code.
12. Go to the Code Spell Checker settings. Notice that there are now 77.
