Get-ADGroup -Properties Member instead of Get-ADGroupMember to in AD rolemodel script

[rschouten97]

Get-ADGroupMember fails with "an unspecified error" when it contains deleted users from foreign domains.
As this does give insight to the groups with deleted users from foreign domains I would like to keep this.
But when the error occures, log this and retry with Get-ADGroup -Properties Member instead.

Or perhaps it is best to switch it out for Get-ADGroup -Properties Member alltogether as I know it can cause issues when there are more than 1000 members in a group.
