Subject: [PATCH] Cap aniso8601 for python 2.7 environments

aniso8601==8.1.0 * raises ValuError in case of non-string arguments
passed to get_date_resolution and parse_date methods.

It is ok for Python3 envs, but backward incompatible for Python 2.7
where we are passing unicode (at least in unittests).
