Test-DbaLastBackup - Fix -Path workflow restore failure

Set TrustDbBackupHistory to true for -Path workflow since backup
history objects from Get-DbaBackupInformation are valid and should
not be re-processed. Fixes type conversion issue where Select-Object
converts BackupHistory to PSCustomObject, causing Restore-DbaDatabase
to misinterpret them as file paths.
