[manachynskyi]

This PR is going to fix issue with missed 'target', 'rel', 'class' attributes that are available in "Link (with attributes)" Link field widget.

Steps for review

• visit Main navigation menu /admin/structure/menu/manage/main
• edit any menu item
• set 'target', 'rel', 'class' https://i.imgur.com/zSt2ci6.png
• open homepage
• make sure that attributes added to menu link https://i.imgur.com/vYlWjFx.png
• repeat the same for User account menu
  P.S. As User account menu not configured (in current realization of configs and template) to display 2 level links, this condition was removed.
