DSC module fails test if the new Az module is installed

[ricohomewood]

When using this DSC module to install the new Az powershell module the tests will fail although the sub modules are installed?

When the Az module is installed from powershell gallery, this installs all the Az.<sub modules> but the parent Az module is missing so the test fails and says the machine is non-compliant.

This is on a Windows Server 2016 - Datacenter Core VM in Azure.

Config Block used:

PSModuleResource Az 
        {
            Ensure = 'Present'
            Module_Name = 'Az'
            RequiredVersion = '1.4.0'

        }

The result of this run on the VM is below running Get-Module -ListAvailable:

PS C:\Program Files\WindowsPowerShell\Modules> Get-Module -ListAvailable

    Directory: C:\Program Files\WindowsPowerShell\Modules

Notice this fails to read in the parent Az module and thus the test of the DSC module fails.

Further research shows that this is a problem with Powershell which looks like it will be fixed in a newer release of Powershell Core: https://github.com/PowerShell/PowerShell/issues/8125
