Repository: microsoft/vscode (TypeScript) — Bug Fix

Issue:
`WorkspaceConfiguration.get` & `WorkspaceConfiguration.inspect` seems to return the wrong values when using Profiles
I'm not sure if this only applies when debugging or not, but here is the setup when this happens:

1. Set a setting, e.g. `"gitlens.graph.dimMergeCommits": true` in the default profile
2. Create a new <whatever> profile, and ensure that the above setting doesn't exist in it
3. Open the code to an extension (that will call `WorkspaceConfiguration.[get|inspect]`) in a window on the default profile
4. Start debugging the extension a launch config with `--profile=<whatever>`
5. :bug: see that `workspace.getConfiguration('gitlens').inspect('graph.dimMergeCommits') will return an object with a `globalValue` of `true`, but that is not correct because the profile doesn't have that setting set, and the default is `false`
6. :bug: see that `workspace.getConfiguration('gitlens').get('graph.dimMergeCommits') will return `true`, but it should be `false`

Things seem to work fine as long as the default profile doesn't have the value set, but once it does you get the behavior above.

Discussion:
Based on what I could notice, it doesn’t seem to be a _debug only_ issue. 

It isn’t a problem for most of my extensions (at least no user complained up until now) but I noticed such behavior while working with my Project Manager extension, because the `globalStorageUri` value doesn’t respect the current profile. Then, looking a bit more, I noticed such conflict too, which blocks me from use different settings for each profile, unfortunately.

BTW, I created https://github.com/microsoft/vscode/issues/160466 to report the `globalStorageUri` issue
@eamodio Wondering if you tried insiders to see if this issue still exists?
@sandy081 yes, insiders is my daily driver. And this issue has been around since the beginning of profiles just finally dug more into it to get a better idea of what was happening to report it. 
Sorry about this. It is specifically happening for settings contributed by extensions. I am not updating the model after they are registered. Fixed it.

To Verify:

- Create a sample extension with following setting and extension code
```json
"contributes": {
		"configuration":[
			{
				"title": "Test configuration",
				"properties": {
					"test.enabled": {
						"type": "boolean",
						"default": false
					  }
				}
			}
		],
}
```
```ts
import * as vscode from 'vscode';
export async function activate() {
    console.log(vscode.workspace.getConfiguration().get('test.enabled'));
}
```
- Install this extension in default profile and open update the `test.enabled` setting to `true` in user settings
- Create a new profile from the default profile
- Reload the window
- Make sure you see `false` in the console.
