WinGetPackage does not work when source is removed

[Gijsreyn]

Brief description of your issue

I was playing around with the winget-cli-restsource in combination with the WinGetPackage DSC module and noticed something unexpected.

When I deployed the whole solution and added the source using the winget source add command, everything was working perfectly when I deployed the following:

properties:
  resources:
    - resource: Microsoft.Windows.Developer/DeveloperMode
      directives:
        description: Enable Developer Mode
        allowPrerelease: true
      settings:
        Ensure: Present
    - resource: Microsoft.WinGet.DSC/WinGetPackage
      directives:
        description: Install PowerShell 7
      settings:
        id: Microsoft.PowerShell
        source: winget
  configurationVersion: 0.2.0

After finishing up my testing with the private REST source, I deleted the resources in Azure. Here comes the interesting part: the source was, of course, still present, and an attempt to re-apply the configuration started to fail even though the source had been defined in the configuration file:

Of course, after removing the source, it worked again. However, this looks like these rough edge cases.

Steps to reproduce

1. Create a WinGet Configuration file leveraging the Microsoft.WinGet.DSC/WinGetPackage resource targetting winget as source
2. Add a new REST source
3. Remove connectivity towards the REST source

Package aren't able to install.

Expected behavior

Package should be able to install.

Actual behavior

An error occurred while connecting to the catalog.
