Remove a stray Delete link from the garden page

A .dropdown-divider and a dropdown-item Delete link sat in the page body, outside
any dropdown, duplicating the Delete in the Actions menu. With the menu open the
page has two visible Delete links, and the 'Delete garden' spec, which clicks
'Actions' and then 'Delete', finds both. The Actions menu already has the
garden's Delete.
