bus: in bus_foreach_bus() don't bother with api_bus if it is NULL

Let's better be safe than sorry, and validate that api_bus is not NULL
before we send messages to it. Of course, strictly speaking this
shouldn't actually be necessary, as the tracker object should not exist
without the bus, but let's be extra sure.
