erp5_computer_immobilisation: Fixup in test

test_apply_model_filled_computer_batch_mode did not pass batch_mode
and was wrongly checking that result is True

Test was passing, because without batch_mode Computer_applyComputerModel
returns Base_redirect, so the result is indeed evaluated as True.
Yet in this case we should expect False, since no changes are applied
