Fixed bug mdev-6705.
After constant row substitution the WHERE condition may be simplified and its multiple equality
may be changed. In this case the references to these multiple equalities from the COND_EQUAL
objects associated with ON expressions must be updated.
Also we have to take into account that this simplification may lead to equalities of the form
field=const that are mutually exclusive with some of the equalities in ON expressions.
