Fix for message comment.

If comment is sent by the user, different structure of the data is sent.
First of all, the type of this message is "message", but it contain
dictionary under 'comment' key, which can be confusing, which contain
needed data (like user id). For this kind of messages, in case of lack
of 'user' in main dict, dict['comment']['user'] will be used for getting
user identifier, while dict['text'] remains as a message text.
