- Fixed DataManagerTest, and added additional coverage to it. All tests in DataManagerTest should pass now.
- Fixed a bug in isFavorited() derived flag, sometimes wouldn't be updated if operations ran in a particular order.
- Made some small changes and fixes to LocalDataManager / DataManager to support the DataManagerTest fixes.
- Added createAttachment variants, including a createAttachment from Uri method to the QAController.
- Added and implemented a derived QuestionItem::hasAttachments() method.
