Dealing with assignments in Role configurations, redirects you to the "Policies" tab after every action. The "Assigments" tab should automatically be selected after adding/removing role assigments

For instance, when clicking the "Delete" button in the modal below, the user should see the content of the "Assigments" tab when the page refreshes

Note when merging up: Anchor is named ibexa-tab-users-and-groups (not users-and-groups) in Ibexa 4.x
