Right-click 'Refresh' on database now updates object store view, also fixed IndexedDB view crash.

The crash was being caused by a null pointer exception in the view constructor since _database in Resources.IDBDatabaseTreeElement was not loaded/stored before the view was constructed. Adding a null check before constructing the view stops the exception.
