Remove un-needed line in TimerTask

[fzakaria]

Removed self.value = value in TimerTask#timeout_task

This line was probably added as a copy-mistake from the above
method (execute_task).

I ran brake spec SPEC=spec/concurrent/timer_task_spec.rb and the tests pass.
I can't see why the need to self-assign the variable here.

Some more notes on TimerTask we are discussing:

1. try? on event is confusing or rather has no documentation.
2. there should be explicit mention that TimerTask is a fixed delay rather than fixed rate
   References to https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledFuture.html would be good here.
3. If the delay + timeout_interval is shorter than the length of time the task takes; concurrent tasks will run.

Thank you for taking an interest. There is ongoing effort to rewrite TimerTask to something more simpler and maintainable #829 the code there is incomplete though, I have more changes locally.

[pitr-ch]

Please wait until I finish and push the changes I have. Let's address points you had on the new implementation.

@pitr-ch I think you commented on the wrong PR

[pitr-ch]

Actually I did not but the comment is not understandable 😁sorry
I meant to ask you not to invest more time in the TimerTask until I push the changes to the other PR, I am trying to prevent effort duplication.

[fzakaria]

Gotcha.
