The TimerEvent::AppendTaskHandle event should always be sent before The TimerEvent::FinishTask event.

[gamife]

Describe the bug
When the task instance is running too fast, The TimerEvent::FinishTask event will be sent before The TimerEvent::AppendTaskHandle event. Subsequent task instances will not run again.

To Reproduce
Steps to reproduce the behavior:

1. add tokio::time::sleep(std::time::Duration::from_secs(2)).await before
   

   delay-timer/src/timer/timer_core.rs

   Line 343 in 1fd9d17

   self.send_timer_event(task_id, tmp_task_handler_box).await;

2. run a repeat task with maxinum_parallel_runnable_num = 1;
3. If the task instance ends in less then 2 second, it will get parallel_runnable_num>=maxinum_parallel_runnable_num doesn't run it.

Expected behavior
Subsequent task instances can run again.

Thank you @gamife very much for your support of the project. Due to work reasons, it is difficult for me to find time to do the open-source project now. Would like to invite you as the maintainer, I wonder if it is convenient for you

Thank you very much for the invitation and for all the hard work you’ve put into this project. However, I don’t have enough experience and my abilities are limited to take on this responsibility. I suggest you find someone else who is capable of taking on this position.
