    Invalid reference to self in functional test test_scrubber.py

    In the test_scrubber.py the function wait_for_scrub() makes a
    reference to self even tho it is not a member of any class and
    has no such reference in its scope. This patch makes that
    function a method in the test class so that it can assert the
    failure which it intends.

    fixes bug: 1163617
