Barion locale(language also) select has not options, but it's required

+1 Any solution to this?

I attach a patch with a possible fix of adding the language list as an array as the Drupal select element needs it.

I tried to use enums but then I got Error: Object of class Barion\Enumerations\UILocale could not be converted to string in form_select_options() (line 110 of /app/web/core/includes/form.inc). So adding a simple associative array seemed easier to deal with.

Patch with enums.
