When going through 4-way handshake, the station side reports CTRL-EVENT-CONNECTED after having sent out EAPOL-Key msg 4/4. The AP side reports AP-STA-CONNECT after having completed processing of this frame. Especially when using UML with time travel, it is possible for the connectivity test to be started before the AP side has configured the pairwise TK if the test is triggered based on CTRL-EVENT-CONNECTED instead of AP-STA-CONNECT. Add explicit wait for AP-STA-CONNECT in some of these cases to reduce likelihood of reporting failures for test cases that are actually behaving as expected. This shows up with "dev1->dev2 unicast data delivery failed" in the test log. Do the same before requesting reauthentication from the station side since that has a similar issue with the EAPOL-Start frame getting encrypted before the AP is ready for it.
