auto-t: Fix testAP

Fixed two issues:

1. There is no longer a dbus exception when switching to AP mode when
   connected in station mode so that assert was removed.

2. After the device/station change the timing must have changed, causing
   autoconnect to take over before an explicit connect call. Added a
   psk provisioning file that disables autoconnect.
