*   Allow testing `discard_on/retry_on ActiveJob::DeserializationError`

    Previously in `perform_enqueued_jobs`, `deserialize_arguments_if_needed`
    was called before calling `perform_now`. When a record no longer exists
    and is serialized using GlobalID this led to raising
    an `ActiveJob::DeserializationError` before reaching `perform_now` call.
    This behaviour makes difficult testing the job `discard_on/retry_on` logic.

    Now `deserialize_arguments_if_needed` call is postponed to when `perform_now`
    is called.

    Example:

    ```ruby
    class UpdateUserJob < ActiveJob::Base
      discard_on ActiveJob::DeserializationError

      def perform(user)
        # ...
      end
    end

    # In the test
    User.destroy_all
    assert_nothing_raised do
      perform_enqueued_jobs only: UpdateUserJob
    end
    ```
