Trailing comma behaviour has changed between 4.3.1 and latest

[tom-thorne]

Version 4.3.1 format stream used to output trailing commas if csvStream.write(values) was called with too short an array than the first row. That meant that all rows had the same number of commas.

The latest doesn't any longer - so some rows can have fewer commas. This is not useful IMO

Output from 4.3.1

locationName,locationId,categoryGroupId,sort,displayCode,categoryIds,title,shortDescription,imageUrl
,G1-n6,ga,,,,Beer,,
,G2-n5,gb,,,,Red,,
6,loc6,gc,,,,White,,

Output from 4.3.6

locationName,locationId,categoryGroupId,sort,displayCode,categoryIds,title,shortDescription,imageUrl
,G1-n6,ga,,,,Beer
,G2-n5,gb,,,,Red
6,loc6,gc,,,,White

I don't know if this is a bug or a breaking change, but I've reverted to 4.3.1
