    introspect: Fix whitelist check
    
    The whitelist is a list of well-known D-Bus names, which we then search
    for the unique name we get from the method invocation - unsuccesfully.
    
    Fix this by watching the bus for any name in the whitelist in order
    to maintain a map from wel-known to unique name that we can use for
    matching.
