[m106] Fix PauseOrFreezeOnWorkerThread with nested Worklets.

Worklets can use the same backing thread which means we can have
nested WorkerThreads paused. If a parent WorkerThread gets deallocated
make sure we don't access anything after it is deallocated once the
nested event queue is released.

BUG=1372695
