JdbcRepository uses the wrong jobInstanceId when getting all job executions with null job instance

when getting all job executions while passing null job instance, JdbcRepository uses the wrong job instance id to retrieve job instance, and hence the wrong job instance is set to the job executions.

This issue only occurs when passing null job instance to getJobExecutions(JobInstance) method. Also need to check other types of repository and see if the same issue exists.

around line 572:

if (jobInstanceId == 0) {
   jobInstanceId = rs.getLong(TableColumns.JOBINSTANCEID);
}

jobInstanceId variable is inside a loop, and its value from previous iteration will carry over to the next, and since it's already non-zero, it will skip the above check and is incorrectly used in the new iteration.
