Description:

• fix SettingsVC readding on pane change;
• fix native ui session restoration losing forward history and re-restoring

Steps to test this PR:

1. Open settings, switch settings panes, validate hover on rows still works and the "paw" appears on links in settings and remove device in sync
2. Restart the browser with Reopen all windows session and Settings tab active: when the settings tab is restored - validate it‘s restored to the same pane as before closing; select another settings pane, validate it‘s selected from the first click
3. Navigate between settings pane, validate no back history items are created for each pane
4. switch to another tab, switch back to Settings, validate the same pane is still open
5. Switch to bookmarks, navigate back, validate the same pane is still open
6. Don‘t close the settings pane; Navigate from a new tab to SERP, to about:bookmarks, to about:settings, validate back/forward is working correctly,
7. return forward to the settings page, switch another pane; switch to another settings tab, validate selected settings pane is kept for each settings tab when switching.
