Stop narrowing deltas when raw

If the delta or the base item is raw, the "narrow" method does not
work adequately (because of pitfalls related to comparison of raw
values). Perhaps the simplest and most effective solution is to
disable narrowing the delta if either the delta or the base item
itself has some raw parts.

This resolves MID-7918 (the part related to ignoring modifications
of "const" based configuration properties).
