tests: Wait for AP-ENABLED

It takes some time for hostapd to complete AP startup. In some cases,
this could potentially result in station starting a scan before the AP
is beaconing or ready to reply to probes. To avoid such race conditions,
wait for AP-ENABLED before going ahead with the test cases.
