One of the tests expects a roam to a certain BSS, but there's an extra hostapd instance (use by another test) making it random which BSS IWD roams to. This hostapd instance has been disabled for this test. The second issue was waiting for the no-roam-candidates event. The default wait is 10 seconds, which can sometimes take longer since IWD will perform a full scan after a roam scan. Increase this timeout to 20 seconds to guard against that.
