Scheduler portal job output for Scala tasks is wrong

[aminelouati]

How to reproduce the issue:

1. Configure the scheduler to the non fork mode: in config/scheduler/settings.ini set pa.scheduler.task.fork=false
2. Submit a workflow with scala task with the following implementation

for( a <- 1 to 50){
         println( a );
}

3. Go to the output of the task in the scheduling portal and check that what is displayed is different from the expected output. A single number is displayed in each line.
