TAJO-1875: Resource leak after a query failure
The main reason is that wrong resource release routine.
When TaskManager receives a task start event ```e```, it checks that
```e``` is the first task start event of the current eb. If so, it create a
context for the current eb. Here, if an error occurs while creating a eb
context, the resource assigned for ```e``` must be released.
However, in the current implementation, the resource release routine
requires a task attempt id which will not exist with an eb start failure. As a
result, resource manager loses the resource assigned for ```e```.
