    Fix test_request_too_large_no_content_length failure

    Webob >=1.7.0 change its way to check if body is readable [1],
    The is_body_readable() method returns False now. request.content_length
    will be set when set request.body automatically, and if
    request.context_length is None request.body will return returns b''.[3]
    So just set request.body in test.
