`select hierarchy` is treated in similar way as we're selecting single element from outliner. When `object_select_hierarchy_fn` is called for the first time, we clear select flag for all elements in `outliner_item_select`. This causes issue when `select hierarchy` is called for multiple elements. So fix is to not touch select and activate flags when `OL_ITEM_RECURSIVE` flag is set. This also fixes the hierarchy selection when "sync select" is OFF.
