Fix args for update func in  _resource_present()

Update methods are decorated with get_by_name_or_uuid_multiple which
expects resource id (or name) in kwargs with exact <resource_id> key
or as positional arg. _resource_present() was calling update with
name=name which was causing "IndexError: pop from empty list"

The patch fixes the issue by using positional arg.
