Added test for TaskJobService.populateComposeTaskRunnerStatus

[corneil]

Added test for org.springframework.cloud.dataflow.server.service.TaskJobService.populateComposeTaskRunnerStatus. Fix DefaultTaskJobServiceTests to use just created ids in subsequent methods. Fix error in JdbcAggregateJobQueryDao with fixed schema in parameter.

The code involved in determining CTR status in tasks/executions:

• TaskExecutionController.getCtrTaskJobExecution
• TaskExecutionResource.getTaskExecutionStatus

The code involed in determining CTR status in tasks/thinexecutions:

• JdbcAggregateJobQueryDao.FIND_CTR_STATUS
• JdbcAggregateJobQueryDao.populateCtrStatus
• TaskExecutionThinResource.getTaskExecutionStatus
