test(hub): read the transport wherever it is split

spa_source.transport_files() takes the classic transport*.js scripts
from the hub's shell, in load order. Every test that read transport.js
reads them all, the Node harnesses run them joined as one scope, the
chat probe loads each, and the desktop shell must load them in order.
