Audit messages currently don't contain the mediation class which can make them less clear than they should be in some circumstances. With newer mediation classes coming this potential confusion will become worse. Fix this by adding the mediatin class to the messages. Signed-off-by: John Johansen <john.johansen@canonical.com>
