    Don't return the sensitive information to user

    We return back the sensitive information to user
    when some exceptions happened, for example,
    when DBError happened, we return the whole sql
    statement to user, it's not safe.
    This patch changes to return the message if the
    exception is the HeatException, otherwise the message
    won't be revealed to user.
