ros2 Iron: rqt_bag displays wrong type in raw view

[tcm0116]

When displaying the raw view for multiple topics in a bag file, rqt_bag always uses the same message type for all raw views:

This can be recreated by:

Terminal 1:

1. source /opt/ros/iron/setup.bash
2. ros2 run turtlesim turtlesim_node

Terminal 2:

1. source /opt/ros/iron/setup.bash
2. ros2 bag record -a -o rosbag
3. After several seconds, press Ctrl+C to stop the recording
4. rqt_bag rosbag
5. Right-click on /turtle1/color_sensor and select View and then select Raw
6. Right-click on /turtle1/pose and select View and then select Raw
7. Select the Next frame button in the main toolbar until data is displayed in the raw views
8. The message type and data layout in both raw views will be turtlesim/msg/Pose
9. Select the Next frame button in the /turtle1/color_sensor__Raw view
10. The message type and data layout in both raw views will be turtlesim/msg/Color
11. Select the Next frame button in the /turtle1/pose__Raw view
12. The message type and data layout in both raw views will be turtlesim/msg/Pose
