Incorrect slurm_job_id in tokens for array jobs

[hailihu]

When submitting jobs to slurm, the slurm_job_id is put in the token. This is obtained from the environmental variable $SLURM_JOB_ID on the worker node. However, for array jobs, the slurm_job_id in the token does not match slurm-xxx.out. For array jobs, ${SLURM_ARRAY_JOB_ID}_${SLURM_ARRAY_TASK_ID} should be stored in the token as jobid.
