Fixed low bug EXT-4311 (Order of items in 'Favorites Bar' folder remains non-changed if change its order in the 'Favorites Bar')

-- reason: there was two places where identical resorting of Favorite landmarks functionality was implemented: InventoryBridge & Favorite bar.
    It was not impelnmented properly in favorites bar: LLInventoryObserver::SORT flag was not set after d-n-d.
-- fix: moved identical functionality to update & save order of Favorite landmarks from these places to Inventory Panel
