When configuring wpa_supplicant all we care about is that it
received the configuration object. wpa_supplicant takes quite a bit
of time to connect in some cases so waiting for that is unneeded.
This also increases the DPP timeout which may be required on slower
systems or if the timing is particularly unlucky when receiving
frames.
First disconnect wpa_supplicant to make sure it wont miss frames if
it decides to connect. Also alter the order of things for the
configurator test so autoconnect doesn't start until after hostapd
is up (avoids additional scanning and delays)
