[REVIEW: 3-6-0] fdo#55241 updating of indexes is broken

Hi all,

commit 859018061956b1937c7be3809a9858cbd610fa9c fixes yet another STL
conversion bug (no offense meant, Noel--your work is much appreciated).

As a side note: I have to admire the ingenuity of authors of the TOX
implementation in Writer, whose glorious idea to define virtual
operator== and operator< (with unrelated semantics) for the
SwTOXSortTabBase class hierarchy allows us to write code like:

if(*pOld == *pNew)
{
    if(*pOld < *pNew)
...
