error: defines defaults multiple times.

    error: def bulk_update/4 defines defaults multiple times. Elixir allows defaults to be declared once per definition. Instead of:

        def foo(:first_clause, b \\ :default) do ... end
        def foo(:second_clause, b \\ :default) do ... end

    one should write:

        def foo(a, b \\ :default)
        def foo(:first_clause, b) do ... end
        def foo(:second_clause, b) do ... end

    resource TaskApp.TodoTasks.TodoTask do
      define :bulk_update, action: :bulk_update, args: [:ids, :attrs]
      ...
    end
