Records without a name fail poorly

[davydog187]

If you have a record without a name field, you'll get an error like

** (FunctionClauseError) no function clause matching in Ecto.Changeset.add_error/4

    The following arguments were given to Ecto.Changeset.add_error/4:

        # 1
        #Ecto.Changeset<action: nil, changes: %{name: "match", type: %{"fields" => [%{"name" => "uuid", "type" => "string"}, %{"name" => "type", "type" => "string"}, %{"name" => "league", "type" => "string"}], "type" => "record"}}, errors: [], data: #AvroEx.Schema.Record.Field<>, valid?: true>

        # 2
        :type

        # 3
        %{name: ["can't be blank"]}

        # 4
        []
