Resolve "broken breadcrumb in admin/user when switching tabs"

What does this MR do?

Fixes breadcrumbs as described in #47419 (closed).

Are there points in the code the reviewer needs to double check?

The breadcrumbs now stay the same when navigating the tabs but i made a small modification when adding/editing an identity. I think like this it's the most intuitive way, please double check
