clean ID (#1)

* fix: It base64 error if use with WifiManager

* fix: the device is not work after reconnect wifi

* Remove logging

* Add debug back in, but make default "no log"

* Fix complete annihilation of storage on new pair

- Might fix Mixiaoxiao#103, Mixiaoxiao#139, Mixiaoxiao#147, Mixiaoxiao#184, Mixiaoxiao#198
- Also adds changes by @ruleechen
- Also adds changes by @thiti-y
