tests: Make pmksa_cache_{,opportunistic_}multiple_sta more robust

Clear wpa_supplicant scan cache before starting these test cases since
the ROAM command depends on the correct BSS entry being found.
scan_for_bss() does not enforce that correct entry to be present if
there was an earlier BSS entry with the same BSSID.
