Selecting and unselecting Serafin makes an unbuildable config

[DrRataplan]

Repro steps:

1. Make a new jinks app
2. Select the Serafin Correspondence blueprint
3. Unselect the Serafin Correspondence blueprint
4. Observe the theme.colors.palette to be set to 'dark'
5. Generate the app

Expected:

The app can be generated

Actual:

The app fails to generate with this error:

{
  "column":9,
  "code":"cpy:not-found",
  "value":null,
  "module":"/exist/data/expathrepo/jinks-10.0.0/modules/cpy.xql",
  "line":70,
  "description": "Input file /db/apps/jinks/temp/demo/resources/css/palette-dark.css not found"
} 

Root cause

Two-fold:

• The theme.colors..palette is set when unselecting a profile_, not what I expect
• The dark palette lives in the Serafin profile. I do not see the link between Mikołaj Serafin and darkness

confirmed, still a thing, still breaking

easy thing would be to remove the palette configuration, I can't see a noticeable difference with the default palette
