Previously we were seriously abusing the virConnectPtr struct by
getting an instance with test:///default URI, and then munging
the private Data to point to XM's struct. I stopped opening a
connection, and just have a struct directly initialized with
the test data, so there's no need to explicitly close it - its
a little clearer if you look further up the test case, rather
than just this bit of diff context.
