Fixes #955

There are currently two public APIs for users to get the result of a goal.
This change deprecates one of the APIs, which was considered to be unsafe as
it may result in a race with user-code and raise an exception.

Edit: The only "new" test failure I see is on Linux

"ros2topic.src.ros2.ros2cli.ros2topic.test.test_echo_pub.test_echo_pub"

But I find it extremely unlikely that a change to rclcpp_action would cause ros2topic to misbehave. I think this change is okay to merge, pending a second reviewer.
