Fix remote image language priority to prefer English over no-language

Previously, images with no language were ranked higher (score 3) than
English images (score 2), causing poorly rated languageless images to
be selected over well-rated English alternatives for posters and logos.

Swap the priority so English is preferred over no-language images.
Backdrop images are unaffected as they have their own dedicated sorting.

Add unit tests for OrderByLanguageDescending.

Fixes #13310
