job_id partially cast in to str cause wrong job state

[unkcpz]

Problem manifest in aiidateam/aiida-hyperqueue#30
When the job_id of JobInfo is in int format, the job in joblist is not parsed into correct state. The job in QUEUED is not wait but continuously moving to finish state.

The bug came from job_id is cast into str in _get_jobs_with_scheduler which return List[str] for job_id list but in _get_jobs_from_scheduler may have job_id in any hashable type.
