fix: #8461fix: #8473
For now, for those inactive but uncompleted tasks, they still shown as
Running in `exp show` and `task queue`, we cannot remove them because
they are regarded as running, we cann't kill them because their are no
real process behind them.
1. Now we can examine these false running tasks and mark them as failure
in `queue kill` command. #8461
2. Better msg handle for initliaizing tasks in `queue kill`#8473
3. Add new unit tests for both cases.
4. bump into new dvc-task 0.1.6
