If the types doesn't match in QVariant::compare we do a comparison based
on QString, this may end up indicating a full match, though the we don't
match according to cmp. In this case it would be better if we preserved
the non-matching to avoid breaking ordering.
[ChangeLog][QtCore][QVariant] Fixed ordered comparison between QVariants
that do not match but produce identical toString output.
