Removes dropping note's first comment

Removes dropping note's first visible comment in case of deleted note's author. After adding displaying "deleted" as note's description, first visible comment is now displayed as note's comment. Moves logic of calculating which note comments will be displayed and if note contains anonymous author / comments to the controller.
