Create the interface on the stack, instead.

If close() is called on the query service client while dbus queries
are still in flight, they were left dangling. This change makes sure they are
properly cancelled. Without this, all such dangling queries are maintained by
nepomuk and updated constantly, causing extreme loads, over time.</pre>
