Nautilius causes additional processes to be spawn when launched as shell provider

When nautilus is spawned as a search provider for the shell (--gapplication-service) the nautilus_dbus_launcher_init() appears to be getting called. That is in turn causing org.gnome.Disks and org.gnome.Console to spawn and go through initialization routines fighting for resources which are precious during interactive search.

It's likely neither of them should be spawned in this scenario.
