In the OP_Column opcode, if the cursor is marked NullRow (due to being the
right table of a LEFT JOIN that does not match) and the cursor is the table
cursor for an OR-optimization with a covering index, then do not substitute
the covering index cursor, since the covering index cursor does not have
the NullRow flag set.  Ticket [aa4378693018aa99]
