Manual fix: use base components in unit test templates

`Themed*` components should be used in the actual codebase to ensure we retain theme support.
However, in unit tests these components won't work without a fully-functional `ThemeService` & `Store`.

For this reason, the lint plugin allows `ds-base-*` selectors in unit test templates.
