devicemonitor: keep order of providers and devices

The deviceproviders are added to the array sorted by their rank. Make
sure we keep this ordering when removing a provider.

We use _prepend to collect the devices, use g_list_reverse to get the
devices in the right order; sorted by rank and in the same order as
returned by the provider.
