shill: usage of EventDispatcherForTest and NullRPCIdentifier

Switch tests to use EventDispatcherForTest instead of EventDispatcher,
since EventDispatcher no longer owns a message loop.

Update references for DBusAdaptor::kNullPath to
ControlInterface::NullRPCIdentifier, since RPC identifier is specific
to control interface and opaque to the internal code.
