This fixes some read-past-end issues in assertions that verify the
next row of a table after the last for a specific locale belong to a
later locale. Since those assertions happen without sight of the table
of which the locale's range is a part, they can't tell when the
range's end is in fact the table's end - so they shouldn't have been
reading from a row there. Fix by putting a row there, that belongs to
a nominal locale with index out of range.
