bug: On startup default wallpaper flashes before going to user configured one.

I noticed that when logging in you can briefly see the (albeit beautiful) ambxst wallpaper load first, then the one you selected in the shell settings. This is probably not correct behavior, and indeed might also cause some unnecessary overhead.

Yup, I have to make Ambxst read the JSON files before starting.
