Message:

Fix some unsound task reference manipulation and locking

In some operations that take task ID as an argument,
there's a possibility of the task being destroyed mid-operation
and a subsequent use-after-free situation.
As a general solution, task_find_by_id() is reimplemented to
check for this situation and always return a valid strong reference.
The callers then only need to handle the reference itself, and
don't need to concern themselves with tasks_lock.
