You have to have the 'dgraph.type" in your dataset and also define the Type Schema.

e.g:

{
    set {
       _:test    <name>         "test"        . 
       _:test    <dgraph.type>  "User".       . 
       _:test_1  <name>         "test_1"      .
       _:test_1  <dgraph.type>  "User"        . 
       _:test    <rel>          _:test_1      .
    }
}

And add the Type Definition

type User {
  name
  rel
}

Now you are able to delete with the patterns you used.
