Sometimes the task menu functions "Terminate", "Terminate with timeout" and "Kill immediately" don't work because a wrong job name is used

Current Situation

The task functions

• Terminate
• Terminate with timeout
• Kill immediately

call the JobScheduler command <kill_task... /> which need the task id and the job name.
If the job name is undefined or does not correspond to the task id then the functions don't work.
In the following situation the job_name is undefined:

• The job has a lock.
• A task of the job is running.
• In the Locks tab you can click on the task which holds the lock and you get the task details on the right hand side inclusive the menu with above functions.
• If you use one of these functions then the job_name is undefined.

It can not be excluded that other clicks cause the job name is set undefined or false.

Desired Behavior

The task menu functions should work in every cases.
