Menu management - Right hand side of the menu panel switches to create "new menu" option while moving the menu items on left hand side

1. Login to CMS as admin/editor
2. Go to channel manager >> select any channel >> Edit channel >> Edit menu
3. On the left hand side of the edit menu panel, you see the list of menus.
4. When you select a menu, on right hand side you see the respective menu configs & options.
5. Now drag the menu Jobs to last

Expected - Jobs menu should be drag-able & right hand pane should show jobs info
Actual - Jobs menu is drag-able, right hand pane switches to create new menu item option and below exceptions are shown.
