Python 3's urllib changed the request object so that instead of having a
get_data method, there's now just a data attribute. It turns out
that this attribute also existed in Python 2, although it wasn't the
official API. This change modifies the idonethis tests to use that
everywhere.

Ran rbintegrations unit tests.
