handle
Call this method to add, update or remove drafts in conversations from local database.
This method will create a new conversation and a new draft message if conversation ID is null, based on the users and groups parameters. A one to one conversation will be created if there is only one single recipient, otherwise a one to many will be created.
In case of the conversation ID is not null and the conversation already exist, if the text and the attachment are null, the draft will be deleted, otherwise the draft will be updated.
The completion callback in this method is useful when an error occurred while updating or creating a draft in the local database or when the message is added, updated or deleted successfully in the local database.
