Dataflow Operators - use project and location from job in on_kill method. (#18699)
Reason why we need this is because we can have situation where project_id is set to None but we define it in the dataflow_default_options. Job will start normally without error but in case when we decide to mark running task to different state we will get a error that the job does not exits.
