ADOrganizationalUnit: throws an exception when parent path does not yet exist

[oliveirt]

Details of the scenario you tried and the problem that is occurring

Where a configuration contains both a Parent Organziational Unit and a child of that Parent, it is not possible to successfully call either Get-TargetResource or Test-TargetResource, as they throw an exception where the Parent object doesn't exist.

Verbose logs showing the problem

Suggested solution to the issue

The resource should be returned as being absent, rather than throw an exception.

The DSC configuration that is used to reproduce the issue (as detailed as possible)

Configuration testConfiguration {
    [CmdletBinding(SupportsShouldProcess=$false, PositionalBinding=$false)]
    param(
    )

    if (!$PSBoundParameters.ContainsKey('OutputPath')) {
        Throw "A OutputPath parameter is mandatory." 
    }

    if ($null -eq $Domain)
    { 
        $Domain = Get-ADDomain
    }

    Import-DscResource -ModuleName PSDesiredStateConfiguration
    Import-DscResource -ModuleName ActivedirectoryDsc

    ADOrganizationalUnit DoesNotYetExist
    {
        Name = "DoesNotYetExist"
        Path = $Domain.distinguishedName
        Ensure = 'Present'
    }

    ADOrganizationalUnit ChildA
    {
        Name = "ChildA"
        Path = ("OU=DoesNotYetExist," + $Domain.distinguishedName)
        Ensure = 'Present'
        DependsOn = '[ADOrganizationalUnit]DoesNotYetExist'
    }

    ADOrganizationalUnit ChildB
    {
        Name = "ChildB"
        Path = ("OU=DoesNotYetExist," + $Domain.distinguishedName)
        Ensure = 'Present'
        DependsOn = '[ADOrganizationalUnit]DoesNotYetExist'
    }
}
