control: Add creating config object without a dbus object

For those configuration objects that do not need a dbus object, create
them using a similar method without requiring a dbus object to be given.
Updated each object to correctly reflect their current need of a dbus
object which was driven by moving the creation of the available group
objects to within the event.
