PLUG-4656: MicrosoftDefender - Fix Device Import not working

[jame2O]

📋 Summary

• PR to fix issues experienced by Evida & other customers with Device imports.
• Main change is the ordering of operations to improve performance (likely minimal but there) and a change to the way we check for invalid rows. Evida are having issues with this, so the potential fix is to move to an isnotempty check over != to exclude null DeviceNames
• Removed redundant columns from Device objects as to speed up the query.
