These tests ensure the static transform publisher dies gracefully when

provided with an invalid (or non-existent) transform parameter.

These tests are started by the static_publisher.launch, which loads

parameters into the param server.

We check the output to make sure the correct error is occurring, since the

Note that this *could* cause a problem if a valid TF is stored in the param

server for one of the names; in this case the subprocess would never return
