[AADRoleSettings] Code does not process ActivateApprover parameter correctly when the approver does not exist

[ykuijs]

Description of the issue

The code relies on a try/catch when looking for the provided approvers to detect when the approver does not exist. However when using the filter parameter of Get-MgUser/Get-MgGroup, an exception is never thrown.

This code has to be changed to check for $null instead.
