auto-t: hwsim: wait for method return

Browse Source 
It is not safe to assume that the python dbus implementation will
wait for a method to return. The documentation says this with
respect to reply_handler/error_handler:

"If both are None, the implementation may request that no reply is sent"

To stay on the safe side we should always include the error/reply
handlers and wait for the operation to complete.
