Copyparty deleting history when suddenly system does poweroff.

### Describe the bug
a description of what the bug is

I had history build up for my drives however, when I try to suddenly shutdown it in the middle of startup, it deletes all the history database.

### To Reproduce
List of steps to reproduce the issue, or, if it's hard to reproduce, then at least a detailed explanation of what you did to run into it

Start copyparty service and must have many volumes and once you start you should see uploads are now blocked and then suddenly do systemctl poweroff then in the logs you will see history was deleted when poweroff was done.

### Expected behavior
a description of what you expected to happen

History should not be deleted like this.

### Screenshots
if applicable, add screenshots to help explain your problem, such as the kickass crashpage :^)

### Server details (if you are using docker/podman)

* **docker image:** (variant, version, and arch if you know)
* **copyparty arguments and/or config-file:**

### Server details (if you're NOT using docker/podman)
remove the ones that are not relevant:

* **what copyparty did you grab:** (sfx/exe/pip/arch/...) sfx
* **how you're running it:** (in a terminal, as a systemd-service, ...) systemd-service
* run copyparty with `--version` and grab the last 3 lines (they start with `copyparty`, `CPython`, `sqlite`) and paste them below this line:

### The rest of the stack
if you are connecting directly to copyparty then that's cool, otherwise please mention everything else between copyparty and the browser (reverseproxy, tunnels, etc.)
