    virt: Fix interaction between disk API tests

    A couple of tests were leaking `setUp` state causing the
    `test_can_resize_need_fs_type_specified` test to randomly fail.

    This probably passed in the gate due to the ordering happening to be correct
    everytime. Since I'm using `nosetests`, I happen to be running the tests in
    the 'wrong' order.

    The solution is to have the tests clean up their state between runs.
