[BUG] Wallpaper can't be set declaratively well

[LiAlH4qwq]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest available version of Noctalia.

Bug description

When I set wallpaper.default.path and wallpaper.last.path in ~/.config/noctalia/config.toml, the wallpaper won't be applied, unless I set the it from GUI panel. After that, I found ~/.local/state/noctalia/config.toml got a new option called wallpaper.monitors.eDP-1.path. However, this option is a device-specific option, which seems shouldn't go into declarative config like NixOS config.

Steps to reproduce

1. Set wallpaper.default.path and wallpaper.last.path in ~/.config/noctalia/config.toml.
2. rm -rf ~/.local/state/noctalia
3. Restart session.
4. Wallpaper didn't apply.

Expected behavior

When no wallpaper.monitors.<monitor>.path set, wallpaper settings in wallpaper.default.path and wallpaper.last.path should be applied to all monitors.

Actual behavior

When no wallpaper.monitors.<monitor>.path set, wallpaper settings in wallpaper.default.path and wallpaper.last.path takes no effect.

When only wallpaper.default.path set, the default owl wallpaper shown.

When wallpaper.default.path and wallpaper.last.path set, a grey background will shown.

Which revision are you on? I am unable to reproduce this behaviour locally. (if I delete the state file, the default wallpaper specified in my config correctly pops up). I do not have a multi monitor setup, so we can possibly narrow down the cause if you can repro this with multiple monitors but not with just a single one connected.
