Added logging when a user is added to the default orphan provider.

This will add a statement to the log every time that a patient is uploaded and is added to the orphan provider. Currently the amount of information logged is rather sparse. If this needs to have more information please let me know, however not much more information is provided to the resolve_provider method. For any additional information to be passed, we will have to make changes to the health-data-standards gem, as this seems to be all we can get without doing so.
