    Clean up roles data adjustment

    1. The python_bin var is unused, so it should be removed.
    2. Tasks should be seperated by a newline in order to easily see
       that they are seperate tasks.
    3. The return code of 2 was in the wrong place. It should have been
       where the data was changed, as per the changed_when condition.
    4. With the return code adjusted, the final task's condition also
       needed adjusting to match.
