order_with_respect_to was combined with ordering in the Meta
class for TestResult. Documentation for 1.8 adds a warning that
these meta options cannot be combined. Django1.9 prevents the
installation of models which combine order_with_respect_to and
ordering. The only affected testresults are from 2011.
