Исправить часть warning, обновить некоторые методы из #1222 (#1600)

## Список изменений
Исправлены warning
- Local constant 'expectedUserId' is never 
- Redundant 'Attribute' suffix
- Dictionary lookup can be simplified with 'TryGetValue'
- S6608: Indexing at 0 should be used instead of the "Enumerable"
extenion method "First"
- The keyword 'new' is required on 'AccessKey' because it hides property
'string VkNet.Model.MediaAttachment.AccessKey'
- Using directive is not required by the code and can be safely removed
- The keyword 'new' is required on 'PhotoId' because it hides property
'long? VkNet.Model.Comment.PhotoId'
- Conditional access qualifier expression is known to be not null
- Cannot resolve symbol BotsLongPollUpdatesHandler
- Code is unreachable

Обновил методы из #1222
- ads.getAds
- ads.getAdsLayout
- apps.get
- wall.postAdsStealth
- wall.editAdsStealth
- video.addToAlbum
- friends.areFriends
- friends.getMutual
