Issue on press-permit-core/admin/groups-update_pp.php

Hi I found an issue on add_group_user, basically the variable $data is overwritten on update, then if you have a new insert fails

The error is produced on https://plugins.trac.ww.wp.xz.cn/browser/press-permit-core/trunk/admin/groups-update_pp.php#L33

I add diff
