get-DbaUserPermission does not drop STIG schema

[PianoMatt]

I noticed that get-DbaUserPermission does not drop the STIG schema after a successful execution. I believe the problem is that the code issues the "endSQL" within the context of a user database, and it needs to be in the tempdb.

           Write-Message -Level Verbose -Message "Deleting objects"
            try {
                $db.ExecuteNonQuery($endSQL)
            } catch {
                # here to avoid an empty catch
                $null = 1
            }
