• 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:

  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
