Fix default user permissions and transporturl reconciliation

This commit fixes the followign issues:

1. lack of .* permissions when user is created via transporturl
2. missing reconciliation of the transporturl secret when vhost changes
3. missing permissions cleanup on old vhost
4. missing permissions setup on new vhost
5. missing removal of transporurl finalizer from vhost
