Subject: [PATCH] Fixed possible incorrect escaping of list[str].

By default if you call str() on collection python will escape strings inside of it using single quotes, which will cause "Can't parse custom emoji identifiers json object" error when calling getCustomEmojiStickers.
json.dumps() escapes strings by double quotes so no error occurs.
