When changing credentials old cache prevents connection #195
Description
The old persistency of a device might prevent device connection when the credential secret has been changed.
To replicate:
- Connect a device to MQTT using a credential secret.
- Disconnect and destroy the device.
- While disconnected, wipe the device credentials in the Astarte instance. Then perform the manual registration once more obtaining a new credential secret.
- Do not modify the device persistency folder. Attempt to reconnect the device using the new credential secret.
The device will not return an error but cannot connect to Astarte.
