[PATCH] auto-t: fix two issues with testAPRoam

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.
