The "add an allowed Bluetooth device" algorithm does not actually add the device

[tidoust]

Unless I missed something, step 4.1 in the add an allowed Bluetooth device algorithm handles the case where no device is found in allowedDevices but:

• does not initialize allowedDevice, whereas the starting point is "If one [allowedDevice] is not found"
• does not add the allowedDevice to the storage, which it probably should?

The first issue is probably fixed by just changing required sequence<AllowedBluetoothDevice> allowedDevices; to required sequence<AllowedBluetoothDevice> allowedDevices; = []; in the definition of BluetoothPersistentStorage.

The second issue just requires another step after initializing allowedDevice.deviceId.
