Bug 34043: Remove incorrect spaces

Bug 34043: Remove incorrect spaces

This bug looked cool and safe, but tests highlighted that the
(introduced) newlines were translated into spaces, which is not correct
in the CSV format (i.e. q{"Column 1" , "Column 2"} is not really
correct).

Also, the double quotes were forcibly introduced (semi-correct) but the
tests weren't adjusted.

We should really stop using templates for generating CSV, and use a
library for the task instead of manually crafting them. But that's for
another bug report.

This patch:

* Removes extra spaces in TT-generated CSV headers
* Adjusts the tests to the new format introduced by this report
