Make sure to handle pending messages at start up if a dbus service

is invoked by the dbus daemon.
Prior to this fix, when a service was started by the dbus daemon,
the first dbus call sent to it was being held back till the next
dbus call was performed, resulting in a long timeout for the first
unhandled call and a delayed answer.
