auto-t: update FT-over-DS test for new behavior

The FT-over-DS procedure now authenticates with multiple BSS's
upon connecting. This causes list_sta() to return our address for
any authenticated APs. It has now been changed to work with this
new behavior, as well as a check that the station fully connected
to the expected AP initially.
