- discontinue support of pa.scheduler.job.removeFromDataBase=false, which implied executing joined tables queries constantly (decreases performance and disallow some indexing)
 - add 3 indexes in JobData (submit_time, scheduled_time_for_removal, and job_id_status : composite index used to optimize scheduler portal default list jobs query)
 - getTaskCounts : avoid joined table query by considering only task statuses.
 - getFinishedTaskCount : fix incomplete list of finished task statuses
 - getPendingTaskCount : add in-error status (similar to pause)
 - adapt db tests
 - add owner column in TaskData to avoid join
 - initialize TaskData.owner using JobData.owner when recovering an existing database
 - TaskData : replace task.jobData.id by task.id.jobId to avoid implicit cross join
 - TaskDBUtils : supress removeTime usage and replace jobData.owner by taskData.owner
 - BaseServiceTest : add SQL debug info
 - MockSchedulingInfrastructure : print unexpected exceptions
