The single Q_FOREACH use here is simple, as it's over a local variable
that just isn't marked as const due to the way it's constructed, and
the loop body clearly doesn't modify the container, so the protective
copy that Q_FOREACH performs is not needed. But std::as_const() is, to
prevent a detach() (attempt). Add that.
