Today we rely on registering the channel after registering the task to be cancelled to ensure that the task is cancelled even if the channel is closed concurrently. However the client may already have processed a cancellable request on the channel and therefore this mechanism doesn't work. With this change we make sure not to register another task after draining the registrations in order to cancel them. Closes elastic#88201
