Bug 1539039 finish worklet before destination stream is destroyed r=padenot AudioDestinationNode, AudioContext, and Worklet are part of the same cycle. Any of these may be unlinked before another. The unlink process for this cycle is the notification that the worklet will no longer be used, but the worklet uses the destination stream to send a message to release graph thread objects and so must do this before the stream is destroyed.
