James Prestwood d232edde72 auto-t: replace waiting for network with device
Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.

This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
