Get-UpdateCatalogDownloadInfo sometimes returns null, which later causes an exception

[mlongwell]

Occasionally, LatestUpdate will sometimes throw an exception.

During Get-LatestServicingStackUpdate.ps1, line 97 throws an exception, stating that $downloadInfo is null.

LatestUpdate/LatestUpdate/Public/Get-LatestServicingStackUpdate.ps1

Line 97 in 50e8c79

$downloadInfo | Add-Member -NotePropertyName "Version" -NotePropertyValue $ver

This variable is supposed to be set on line 94 while calling Get-UpdateCatalogDownloadInfo, but it looks like this function occasionally returns null:

LatestUpdate/LatestUpdate/Public/Get-LatestServicingStackUpdate.ps1

Line 94 in 50e8c79

$downloadInfo = Get-UpdateCatalogDownloadInfo @downloadInfoParams
