Add the 'name' key to the IoT tests group

The group template was created after 9dc1fafa was merged, which removed all instances of the 'name:' key. However, this turned out to break test submission, which is why it was then reverted in 79a2b0df.

Unfortunately, I did not realize that the new IoT group was missing this field, which means that 'name:' was never added back there and IoT image test submission is broken.
