HPCC-9867 CSV spray incorrectly splitting records with nested quotes

Fix for quote handling problem.

First quote char switched on the quote handling and the second switched it off.
If there are more qoute char(s) (e.g.:double qoute) in the field the quote
handling remained off and any '\n' character interpreted as a record
terminator.
