Ensure bluetooth recovers if Dbus gets restarted

[bdraco]

Until this merging, manually reloading the bluetooth integration should work around the issue.

Proposed change

If Dbus gets restarted out from under us everything will fail to connect with Method "Connect" with signature "" on interface "org.bluez.Device1" doesn't exist because the devices will no longer be available on the bus. We need to restart the scanner so it reconnects the devices to the bus if everything has gone quiet.

This should fix the issues were users reporting bluetooth stops working overnight when the host installs updates and restarts services.
