ltss does not survive a restart from home assistant restart gui

Took me a while to figure that one out. When you use the "Restart" option in Home Assistant in Developer Tools/YAML you get the following exception in the logs, resulting in ltss not logging anything more into the database. Going down to the console and restarting everything there gets everything running up again as it should (meaning stuff gets written into my timescaledb).

Pretty sure at some point back in time, this worked without that hitch, so must have been introduced in some of the latest HA versions. Currently using 2024.10.4.

This error originated from a custom integration.
