Device History does not show “Data sync” and Unspecific” events anymore

Device history no longer shows “Data sync” and “Unspecific” events. If users still want to check for those events, they can query the thing_history collection:

• "DataSync" history events can be recognized in thing_history collection as:

  {"change.0.actionType": "UNTRACKED"}

   

• "Unspecific" history events can be recognized in thing_history collection as:

  {"change":  {"$eq":null}}
