Update event initialization

Using a null dbus message to the event signal will perform the necessary
steps to initialize the event parameters using the given signal
handler's function directly.

i.e.) In the case for subscribing to PropertiesChanged signals,
initially the given property must be read. When the PropertiesChanged
signal struct is given a null message, it finds the property, reads the
value, and then can perform the given signal handler function directly.
This produces the same functional path as receiving a PropertiesChanged
signal containing the property value within the message.
