testAvailableServicesServer1 Failure All services are started, errors=2

The services that fail to start are the recent unified invoker additions.

There are not binding for them in varia\src\resources\services\binding\sample-bindings.xml, so they should be added there (Branch_4_2 and HEAD)

I suspect this affect a series of other tests, as well.
