Remove delete button from Reorder Children page

Problem/Motivation

The delete button on Reorder Children page is may be misleading.

Users may believe that hitting the Delete button this page will remove the entity as a child of the page in context, however it actually links to the delete page of the child.

It seems unlikely, and rarely useful that the delete button would actually be used for its current purpose.

As discussed externally, I proposed either removing the Delete button entirely, or making use of Drupals hook_entity_operation() to populate the Operations column.

Proposed resolution

Remove the Delete button from Reorder Children page.

• Update tests if required.
