[@microsoft/vscode-azext-azureauth] Removing the trusted extension and signing in to a second account may result in empty subscriptions

[xiaolang124]

Steps to repro:

1. Sign In with Account A using the AzureSubscriptionProvider.signIn() method
2. You can see all the subs of A
3. Click Account -> Manage trusted extensions and remove just used extension
4. Sign In with Account B using the AzureSubscriptionProvider.signIn() method
5. You cannot get any subscription. It returns an empty [ ]

	let disposable2 = vscode.commands.registerCommand('authtest.listSubs', async () => {

		const provider = await ext.subscriptionProviderFactory();
		if (!await provider.isSignedIn()) {
			void provider.signIn();
		}
		if (await provider.isSignedIn()) {
			vscode.window.showInformationMessage('Signed in!');
			var l = await provider.getSubscriptions(false);
			vscode.window.showInformationMessage('Got subscriptions!' + l.length);
		}
	});

Do you have any value for the VSCode setting azureResourceGroups.selectedSubscriptions?

@bwateratmsft I don't think so. I haven't edited the settings. Where can I verify this setting?

I don't have this setting, yet I'm still encountering this problem.
