Subject: [PATCH 02/18] application: Instantiate ShellSearchProvider only when
 registering

Now that the --version flag was implemented using the
handle_local_options virtual method, it is possible that the
Application may exit without ever touching D-Bus. So it is a tad
wasteful to instantiate the ShellSearchProvider when it is never going
to be used. Since we are unreffing it in dbus_register, we might as
well create it in dbus_register.
