autotest: Simplify iterating over network objects

Where the code just needs to find all of the network objects, don't look
for the device objects first because this only adds overhead.  With
the structure now having three levels it can be even more confusing,
especially in getCurrentlyConnectedNetworkName where the outer loop
didn't check for the Device interface.

In getNetworkList don't return after the first device's networks are
listed.
