Fix search index for a financed device

Now with two preference controllers, one for enterprise device and one
for financed device, the search index issue (querying "Financed device
info" in Settings does not show a search result) is fixed. The financed
preference controller is used when the device is a financed device.
Otherwise, the enterprise preference controller is used.
