Fix crash when clearing NRF52 BLE bonds (#6609)

Browse Source 
* Fix crash before clearing BLE bonds

* Prevent clients re-pairing BLE during factory reset
Clients seem able to re-pair BLE after clearing bonds during factory reset, even after advertising disabled. This seems to primarily occur on Android devices, which seem to more actively maintain the BLE connection.
As a workaround, `NRF52Bluetooth::shutdown` swaps the BLE pairing callback to one which actively rejects new connections.
