Andrew Zaborowski f0fb1d2c89 autotests: Add a Preauthentication test
Unfortunately this doesn't currently ensure that the preauthentication
has succeeded and that later the PMKSA from the preauthentication was
used in the transition, only that the preauthentication process doesn't
break the transition.  For now this can be confirmed by looking at the
testrunner -v output to see that the line "EAP completed with eapSuccess"
appears before the following line, and not after:

src/device.c:device_enter_state() Old State: connected, new state: roaming
