[gtksourceview] Fix testdark.xml style scheme

    Fix testdark.xml style scheme
    
    testdark.xml is not installed, it is just a test. But some unit tests
    call gtk_source_style_scheme_manager_set_search_path() with the
    data/styles/ directory from the sources, so the unit tests can run when
    gtksourceview is not installed. So testdark.xml in this case is read,
    and there was a problem with the colors not recognized (the colors are
    not inherited from the parent scheme).
