[Tracker] PATCH: Fixes tracker_get_unique_values_async

[Iago Toral Quiroga <itoral igalia com>]

Hi,

tracker_get_unique_values_async does not work, since the current
implementation tries to access GetUniqueValues Dbus method under the
Search interface instead of the Metadata interface. Find attached a
patch to fix this.
