This pull request addresses

For this case, we may receive a message that only contains self in state_message and is missing the required info object. And in creating meeting logic will call the meetingInfo request. We won’t get the correct URI if no info object, which causes the request to fail.

Also, when creating a meeting object, it assumes a full locus and initializes certain properties (such as destination) based on it, and these properties won’t be updated later.

In this PR, the change ensures that if the locus is missing info, we first create a temporary hashTreeParser to construct a complete locus with all necessary data, and then proceed to create the meeting.
