perform_chunk does not properly set args for structured workers

[SteffenDE]

Similar to #649

Environment

• Oban Pro 1.0.2

Current Behavior

Trying to test a Chunk worker that is also structured using args_schema does not properly populate the args, receiving string keys instead.

Pseudocode:

defmodule MyWorker do
  use Oban.Pro.Workers.Chunk,
    queue: :myqueue,
    size: 25,
    timeout: 1000,
    by: [:worker, args: [:foo]]

  args_schema do
    field :foo, :string
    field :bar, :string
  end

  @impl true
  def process([_ | _] = jobs) do
    foos = Enum.map(jobs, & &1.args.foo)
    :ok
  end
end

defmodule MyWorkerTest do
  use ExUnit.Case, async: true
  use Oban.Pro.Testing, repo: MyRepo

  test "it works" do
    assert {:ok, 2} = perform_chunk(MyWorker, [
      %{
        foo: "a",
        bar: "1"
      },
      %{
        foo: "b",
        bar: "2"
      }
    ])
  end
end

Fails with an error like this:

** (KeyError) key :foo not found in: %{"foo" => "a", "bar" => "1"}
     code: assert {:ok, 2} = perform_chunk(MyWorker, [
     stacktrace:

Expected Behavior

Args should be structured as expected.
