  - Merge "Fix race condition in workmanager inspector disposal" into androidx-master-dev
  - Fix race condition in workmanager inspector disposal
    
    There were two issues:
    1. Testing harness was shutting down primary executor too early,
       not giving a chance to completely dispose
    2. WorkManagerInspector was simply posting message to go to
       "DESTROYED" state => onDispose method could finish before than
        this message was executed => primary executor could be
        shutdown before than this message was executed =>
        livedata observers could have sent some message to
        shutdown executor.
    
    It is a minor issue, because production executor silently
    drops messages sent to closed executor. However, we don't want
    to do that in testing, because lost messages could potentially lead
    to bigger issues. In the workmanager case, those lost messages
    during disposal phase didn't have much value, but for correctness
    now workmanager blocks onDispose until all observers are unregistered.
