Marked some tests as expected failures on Oracle/cx_Oracle<=5.1.3/Python3

    """

    cx_Oracle versions up to and including 5.1.3 have a bug with respect to

    string handling under Python3 (essentially, they treat Python3 strings

    as Python2 strings rather than unicode). This makes some tests here

    fail under Python 3 -- so we mark them as expected failures.

    See  https://code.djangoproject.com/ticket/23843, in particular comment 6,

    which points to https://bitbucket.org/anthony_tuininga/cx_oracle/issue/6/
