Fixed #32128 -- Added asgiref 3.3 compatibility.
Thread sensitive parameter is True by default from asgiref v3.3.0. Added an explicit thread_sensitive=False to previously implicit uses.

Sync functions tend to be written assuming they all run in the main
|

thread, so :func:`sync_to_async` has two threading modes:
|
||||
|
||||
* ``thread_sensitive=False`` (the default): the sync function will run in a

brand new thread which is then closed once the invocation completes.
|

* ``thread_sensitive=True`` (the default): the sync function will run in the

same thread as all other ``thread_sensitive`` functions. This will be the

main thread, if the main thread is synchronous and you are using the

:func:`async_to_sync` wrapper.
