Erroneous warning when running via a systemd service with autorestic in the name

[PHLAK]

Describe the bug

I'm setting up autorestic using systemd services/timers for automating my backups and have decided to name my service file autorestic-backup.service. When running the service a warning/error is displayed saying it found exiting autorestic processes and lists all processes with autorestic in the name. The list of processes shows the autorestic-backup.service processes but no actual autorestic process. It also shows a prompt to unlock followed by an "Unlocking aborted" message.

This doesn't seem to be preventing the service from running but it's erroneous since those services aren't pre-exising autorestic processes and there's no reason to show the message.

I haven't looked into the code but I'm guessing this is due to a naive check that's only looking for processes that contain the word autorestic.

Expected behavior

No warning/error should be shown.

Environment

• OS: Arch Linux
• Autorestic Version: 1.8.3

Additional context

Here's the contents of the autrestic-backup.service file.
