Bug 1027398 - [Flame] Bluetooth Overlays will show before lockscreen

Agree with your suggestion before. But we cannot clear up `this.currentPairing` while we have resumed the pairing process. A user might lock the screen --> unlock the screen --> lock the screen --> unlock the screen. But we only have one flag/restored data to manage pairing cycle. I'm wondering how we handle the pairing cycle if we cannot clean up the restored date. Seem like some dependance in one variable `this.currentPairing`.
