init_node failing under ros2

[mark-goodall]

I get the following error, and the same error if I have rosros imported but try to do the same thing with rclpy afterwards in the same python session, but it works perfectly if I just do the equivalent commands with rclpy in a fresh session.

>>> import rosros
>>> n = rosros.init_node("foo")
Traceback (most recent call last):

Getting the error afterwards with rclpy in the same Python session is expected, as rosros monkey-patches rclpy's API.

rosros has not been tested under ROS 2 Jazzy; seems there have incompatible changes. I will look into this.
