Prerequisites

Steps to reproduce

• Call FindPackagesById() for package JiraPS via the PSGallery NuGet v2 API - example API call: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27JiraPS%27&$filter=IsLatestVersion
• Repeat the same API call for package Microsoft.PowerShell.PSResourceGet - example call: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Microsoft.PowerShell.PSResourceGet%27&$filter=IsLatestVersion
• Repeat the same API call for package Microsoft.PowerShell.PSResourceGet, but this time add a space to the front of the filter string: https://www.powershellgallery.com/api/v2/FindPackagesById()?id=%27Microsoft.PowerShell.PSResourceGet%27&$filter=%20IsLatestVersion

Expected behavior

All 3 API calls return one and only one package (with the latest version) for their respective package IDs

Actual behavior

API call #2 returns invalid NuGet XML response, but calls 1 and 3 work as expected

Of particular interest is:

• <m:count>1</m:count> suggests one <entry> should be present, but there are none.
• <author> should be under an <entry>, not the <feed>. (It's also null for some reason?)
