tests: Verify auto_interworking=1 with partiall matching network

This is a regression test for an issue where scanning sequence could be
terminated if interworking_find_network_match() finds a matching
network, but wpa_s->auto_select is not set. This could stop connection
attempts when auto_interworking=1 is used and the scan results have a
partially matching network and no cred match.
