Null reference object in Test-DNSNameServers

[PHactotum]

When running Test-DNSNameServers receive the comment, "Failed to get the zone information for contoso.com on server DC1.contoso.com...."

This appears to be a result of the Jan 2024 commit Convert scriptblock filter to string filter

I'm not sure how to write this as a string filter that will work. I know the AD cmdlets often cause me to revert to scriptblock filters.

Tested on Windows 10 22H2, with PowerShell 5.1.19041.4291

It's actually Get-ADDomainController -Server $domain -Filter 'IsReadOnly -eq $false' |ft that works so need to fix it. Thank you for reporting. Maybe you could PR it
