Clear DeferredTaskHandler's audio thread ID upon the thread going away.

Clear DeferredTaskHandler's audio thread ID upon the thread going away.

Tracking the thread ID of the (current) audio thread is needed to both
sanity check that code paths and methods are performed on the expected
thread, and ensure safe operation.

In the rare cases where the recorded audio thread is stopped and
terminated by the embedder, first clear out the associated thread
ID. This is needed should a new thread be subsequently created.
