Multi AP setups: OMG won't roam to other AP when original gets offline

[chris-heo]

Describe the bug In multi-AP setups (same SSIDs and Passphrases for all APs), OMG seems to stick to an AP and won't connect to another one if it turns off

To Reproduce Steps to reproduce the behavior:

1. Startup OMG with all APs visible
2. Disconnect power from AP (Ctrl+F "##### AP disconnected from power #####" in log)
3. OMG won't connect to other APs with same SSID, only to previous BSSID
4. Connect AP to power
5. OMG connects to original AP

or: 4. restart OMG 5. OMG connects to another AP

Expected behavior re-scan for WiFi instead to "insisting" on last BSSID or reboot after a given number of fails

Additional context

• Running on ESP32-C3 mini boards w/ framework-arduinoespressif32 @ 3.20007.0 (2.0.7) & toolchain-riscv32-esp @ 8.4.0+2021r2-patch5
• also seeing weird behavior in similar environment: Multiple APs available and visible during bootup but fails to connect. I will file another ticket for that.
