[gobject-introspection] Maintransfomer: fix again paring error domains with unregistered enums

    Maintransfomer: fix again paring error domains with unregistered enums
    
    Previous fix was wrong, as it called to_underscores_noprefix on a
    prefixed type name. The actual fix is to call the transformer to
    do the prefix / type_name split, and turn the latter to underscores.
    Test case included.
